What do baby squirrels eat?
One of the most common questions about these tiny mammals is, "What do baby squirrels eat?" In the wild, their diet evolves as they grow. Newborns feed exclusively on mother's milk, which is rich in fats, proteins, and antibodies to build their immune systems. This milk provides all the hydration and nutrients needed for the first month.
As they transition to solid foods around 7 to 8 weeks, baby squirrels start nibbling on soft items like buds, flowers, and young leaves. Gradually, they incorporate nuts, seeds, fruits, and insects into their diet. Acorns, walnuts, and sunflower seeds become staples, offering the energy required for their active lifestyles.
It's important to note seasonal variations. In spring and summer, fresh greens and berries dominate, while fall focuses on nut storage for winter. If you're observing baby squirrels in your yard, providing a bird feeder with unsalted nuts can supplement their diet without disrupting their instincts — just avoid overfeeding to prevent dependency.
What Does a Baby Squirrel Look Like?
Baby squirrels look dramatically different depending on their age. Knowing what stage a kit is in helps you understand exactly what it needs.

At birth (1–2 weeks): Completely hairless, pink skin, eyes and ears sealed shut. About the size of a human thumb. Completely helpless and entirely dependent on mother's milk.
At 3 weeks: A thin layer of soft fur begins to appear. Still eyes closed. Skin color fades from bright pink to a softer gray-brown as fur fills in.
At 5 weeks: Eyes just beginning to open. Fully furred but small. Ears are open. Starting to look like a miniature squirrel for the first time.
At 6–8 weeks: Eyes fully open, bushy tail starting to develop, beginning to explore and climb. This is when most people find baby squirrels on the ground.
At 10 weeks: Looks nearly identical to an adult but smaller. Fully independent and ready for the wild.

Here's what to feed a baby squirrel based on their age:
| Age | What to Feed | What They Look Like |
|---|---|---|
| 1–2 week old | Esbilac puppy milk replacer only | Eyes closed, no fur, pink skin |
| 3 week old | Esbilac puppy milk replacer only | Eyes closed, light fur appearing |
| 5 week old | Formula + soft fruits (apple, pear) | Eyes just opening, fully furred |
| 6 week old | Formula + soft fruits and veggies | Eyes open, starting to explore |
| 8 week old | Nuts, seeds, fruits, veggies | Active, climbing, bushy tail |
| 10 week old | Full wild diet — ready for release | Fully independent, foraging on own |
What to feed a baby squirrel with eyes closed
If a baby squirrel's eyes are still closed, it's under 5 weeks old and needs formula only — never solid food.
Can squirrels drink milk?
No — never feed baby squirrels cow's milk, almond milk, goat's milk, or human baby formula. These cause severe digestive problems including bloating, diarrhea, and dehydration that can be fatal within hours.
Goat's milk is a common mistake. Many people assume it's a gentler alternative, but the fat and protein ratios do not match what baby squirrels need. The same goes for oat milk, soy milk, and any store-bought milk product.
Why can't squirrels drink milk?

The only safe milk for baby squirrels is Esbilac puppy milk replacer mixed with warm water. Esbilac closely mimics the fat and protein content of squirrel mother's milk and is the formula used by licensed wildlife rehabilitators across the country. You can order Esbilac here — it ships next day with Prime.
What kind of milk do you feed baby squirrels?
The only answer is Esbilac puppy milk replacer. Below are the exact products wildlife rehabilitators recommend — in the order you'll need them.
The exact supplies licensed rehabilitators use — in the order you'll need them.
Microwaveable heat disk that stays warm for up to 10 hours with no cords and no auto-shutoff risk. Wrap in a towel and place under half the box so the kit can move away if too warm.
⚠️ Never use a heating pad that auto-shuts off — a kit that loses heat overnight will not survive until morning.

💡 Keep a bottle on hand before you need it — dehydration is the thing that kills a kit fastest, and it never happens at a convenient hour.

Baby squirrel care tips
Proper baby squirrel care begins with respecting their wild nature. At Private Lands Wildlife, we advocate for minimal intervention to promote healthy ecosystems on private lands. If you're caring for an orphaned kit, consult a licensed wildlife rehabilitator first. Handling them without expertise can cause stress or transmit diseases.
For supportive care, start by creating a safe environment. Use a quiet, warm box lined with soft cloths (avoid towels with loops that could snag claws). Maintain a temperature of 95–100°F for newborns using a heating pad on low, wrapped in a towel to prevent burns. Offer pediatric electrolyte solution like Pedialyte via a syringe — never cow's milk.
As they grow, introduce a balanced diet mimicking their natural one. Feed every 2–3 hours for the youngest, tapering off as they age. Monitor weight gain — kits should double their birth weight (about 15–20 grams) in the first week.

📖 The Story Behind Our Mission
Enjoyed learning about baby squirrels? Dive into the true story that inspired Private Lands Wildlife — Billy Gruett, the 16-year-old Chippewa mail carrier who braved Michigan's wilderness in the 1850s. His legacy shaped our commitment to wildlife habitat.
What to feed baby squirrels: step-by-step
Age determines everything. For kits under 5 weeks (eyes closed), stick to formula. Mix Esbilac powder with warm water to a creamy consistency, feeding 5–7% of body weight per session. Use a pet nursing bottle or syringe for controlled delivery to avoid aspiration.
Once eyes open around 5–7 weeks, introduce solids slowly. Start with softened fruits like apples or pears, pureed if needed. Add vegetables such as broccoli or carrots. Nuts should be shelled and unsalted — pecans and hazelnuts are favorites.
By 8–10 weeks, expand to a varied diet: 50% nuts/seeds, 30% fruits/veggies, 20% proteins like mealworms. Always offer fresh water in a shallow dish. Avoid bread, chocolate, or processed foods.
Feeding tips for baby squirrels
One of the most important things to remember is that baby squirrels cannot drink regular milk of any kind. Cow's milk, goat's milk, and almond milk are all dangerous. Only Esbilac puppy milk replacer should be used as a formula substitute.
If you're supplementing wild baby squirrels, scatter food naturally to encourage foraging. This not only answers what to feed baby squirrels but also promotes their survival skills.
How to feed a baby squirrel
Before you attempt to feed a baby squirrel, wrap it gently in a soft fleece or flannel blanket. A cold squirrel cannot digest food properly — warming it up first is not optional, it's the first step.
Found a baby squirrel? What to do next
First, assess the situation: Is it injured, cold, or covered in flies? If yes, intervention is needed. If not, watch from a distance — mom often returns within a few hours.
If the kit is truly orphaned, gently pick it up using gloves or a soft towel, place it in a warm, secure box with a fleece liner (no terry cloth loops), and keep it quiet. Do NOT attempt to feed it yourself yet.
For prevention, secure trash bins and trim branches near power lines to reduce nest falls. Installing squirrel boxes on your property can provide safe nesting spots, reducing the chance of finding displaced kits.

While most people think of ground or tree squirrels, baby flying squirrels deserve a mention. These nocturnal gliders are found in forests across North America, born in litters of 2–7 in tree cavities or nests. Like their cousins, they start with mother's milk, transitioning to nuts, seeds, and insects. Their care is similar but requires more vertical space for gliding practice. Their membrane wings make them unique — handle with extra care to avoid damage.
Health and common issues for baby squirrels
Baby squirrels face threats like predators, parasites, and malnutrition. Watch for signs of distress: lethargy, diarrhea, or wounds. Fleas and mites are common; a vet can recommend safe treatments.
Nutritional deficiencies like MBD can be prevented with a balanced diet. In rehabilitation, regular vet check-ups ensure they're on track.
When Do Baby Squirrels Leave the Nest?
Baby squirrels typically leave the nest for the first time between 10 and 12 weeks old. At this stage they are fully furred, their bushy tail is developed, and they are strong enough to climb and forage on their own. However, "leaving" is gradual — they don't disappear overnight.
From weeks 10–12 you'll see them venturing out of the nest for short trips, staying close to the nest tree. By weeks 12–14 they are spending more time out than in. Full independence usually happens around 14–16 weeks when they are actively foraging, burying food, and no longer returning to the nest regularly.
Squirrels born in the first litter (February–April) will typically be independent by July. Second litter kits born in late summer (August–September) will reach independence by November before winter sets in. If you're raising an orphaned kit, never release before 14 weeks and always do a soft release — leave the cage open in a safe outdoor spot for several days so the squirrel can come and go at its own pace before fully departing.
Common Mistakes When Caring for Baby Squirrels
These mistakes are made over and over by well-meaning people. Any one of them can be fatal.
Conservation and How You Can Help
At Private Lands Wildlife, we believe private landowners play a key role in squirrel conservation. Planting nut trees, avoiding pesticides, and creating habitats boost populations. Simple actions like leaving leaf litter for nesting materials or installing feeders make a difference.
