Completely normal!!! My DS didn't do any childcare either. He started playschool at 3 and cried for 3 terms and then again cried for 3 terms of kindy and Prep. He is now in grade 1 - had a week or 2 of tears in term one, but has been great since. Childcare would not have made a difference, it's just his personality. He is a well adjusted little boy now and loves school.
