05 — Infant Development: Eyes Open to ~6 Weeks

At roughly five to six weeks the baby becomes much more mobile, but formula is still the nutritional foundation. The goal now is to maintain steady growth while adding safe climbing, a nest site and the first solid foods.

• Continue the 5–7% weight-based volume framework if the baby is tolerating it and gaining normally.
• Keep formula very warm and continue careful syringe technique.
• Do not reduce formula simply because the eyes are open or the baby starts chewing.
• Weigh at the same time each day and look for a steady trend rather than one “perfect” number.

1. 01
   First solid: a nutritionally complete squirrel/rodent block. Henry’s Blocks are one source-specific option; the important point is introducing a balanced block before nuts, fruit or treats.
2. 02
   Offer a fresh small piece daily; young squirrels may shred or play with it before actually eating much.
3. 03
   Once chewing well, introduce healthy vegetables and safe wild browse. Remove seeds, pits, skins or strings that create choking risk.
4. 04
   Add clean fresh water in a secure bottle or shallow bowl.
5. 05
   Do not start with nuts, fruit or treats. Those foods can teach the baby to reject the balanced foods it needs.

As coordination improves, move from the neonatal tub into a secure juvenile enclosure with low-risk branches and an elevated nest box/cube. Increase climbing complexity gradually so a weak or clumsy baby does not have a long fall path.

Most babies begin eliminating independently around this developmental window, but do not stop stimulation simply because the eyes opened. Stop only when you are consistently seeing normal independent urination/defecation.

Keep handling functional rather than social. A releasable juvenile should learn that food, climbing, nest-building and squirrel behaviors are more important than seeking human attention.
