Thanks everyone! He will be in preschool for 2 years so he will be 6 when he starts Kindergarten. (They have to be 5 BEFORE AUGUST 1st, and his birthday is the 21st of August) so he is with mostly 3 year olds in preschool. Next year Sophia will be there too, although I think they will be in different classes (meaning I have to go up there 4 times a day! So glad I only live 2 miles from the school!) He is excited about going today, so we will see. I am going to try and talk to his teacher today to see how he is doing.
