1st week at child care

my 1st son used to cry alot for the first 2 weeks. i stayed with him in the CC for couple of hours and play with him then slowly let him start to seat with his friends and teachers this happen for first 3 days and brought him back home after 12noon then slowly till 3plus after he wake up from his nap have his meal then i bring him back. Then i start to walk out of the CC when i see he gets busy with his friends and teachers. watch him from outside but never allow him to know im there then i start to let him stay for full day.
