Baby guinea pigs will start eating solid food from day 1, but will continue to nurse until about 2-3 weeks old, when mum will start shooing them away. Make sure to separate any males after 21 days to avoid dangerous backbreeding/inbreeding. Babies (up to 6mos) and pregnant/nursing mums should get alfalfa pellets (like oxbow cavy performance) instead of timothy-based ones.
