How would I know if my baby is happy in infantcare? It's easy to tell for a older kid. Planning to send my baby soon.

You can tell baby is unhappy in school if baby cries a lot after school, look unsettling and cranky, i.e. not well rested. It is probably due to new schedule and environment in school. If after 1-2 months your baby is still showing these signs, it shows that probably your baby is unable to settle down in the IFC. Also, do communicate with teachers daily on baby's schedule and activities so to understand more on what is going on in the daytime.
