Here are some ideas that I thought of:
-Find out the routine at the daycare centre so you can start now and try to have it fully developed by the starting date.
-In Lo's activity time play some soft music in the background
-Do sharing activities like placing things in bowls, threading
-Don't panic when you go remember this is the first time your baby is going to be at the centre. It's a different environemnt from home. Your baby will come to know the carers and the environment.
-Sit in the yard for a little while each day, listen to the sounds and point them out. If your in the grass or dirt this will get baby used to different textures as well something they will get used to at daycare.
Sorry pregnancy brain has kicked in and I can't think of anymore
