I have a 5.5 yo who occasionally cries at drop off, sometimes shes tired, sometimes shes just had a rough morning, but shes fine as soon as mom goes. She also cries EVERY time her mom drops her off at school, she is in SK (usually I drop her off and its no problem) she also cried when her mom dropped her off with me at my daugthers birthday party. I think sometimes no matter how fun a dayhome is, kids just want their moms!
