Valentine's Day! at Cooper's Preschool

I got to attend Cooper's preschool Valentines party today, while Troy stayed home with Camry. The kids had a lot fo fun with balloons and passing out love notes to their freinds at school. This was my first time being in Cooper's preschool classroom. The teachers did a great job and the classroom has many fun activities for the kids. Cooper played with Legos and cars during their free time. That was a little disappointing becuase he can do that at home! Well, i guess we at least have his favoite things at home. I never noticed, until today, how much Cooper keeps his hands in his mouth. Anyone know what is up with that?
