Last day of school :(

I just cannot believe it's Brennan's last day of preschool today. I am so sad about it!! He was happy to go today and didn't cling to me or anything. I wanted to cry today as I went to pick him up. I never got a card for the teachers to thank them. I may have to look up their addresses and send them a card. They were so great with him. He made such progress this past year. They sent home with us all the things we had to bring in the beginning of the school year. I brought diapers and wipes. Much has changed!
