Hedgehog babies, also known as hoglets, primarily rely on their mother's milk for nutrition during the first few weeks of life. If you are caring for a baby hedgehog that has been orphaned or is in need of hand-rearing, you can use a specially formulated milk replacer designed for small animals, such as Esbilac puppy milk or a similar product. It's important to avoid cow's milk, as it can cause digestive issues.

As they grow and start to wean around 4-6 weeks, you can introduce soft, high-protein foods, such as:
1. **Wet cat food** - Choose a high-quality, grain-free option that is high in protein.
2. **Insects** - Small mealworms or crickets can be introduced as they are a natural part of a hedgehog's diet.
3. **Hedgehog food** - There are commercial hedgehog foods available that are formulated to meet their nutritional needs.

Always ensure that any food you provide is appropriate for their age and size, and consult with a veterinarian if you have concerns about their diet or health.
