First day of school! (Houston TX)

So my baby girl started her first day in PreK! I thought I was going to be strong but I cried like a baby after seeing her so sad (see pic). I miss her and it's only been 3 hours. Also my son went to first grade and its not like I don't love him but this is his 4th year going to school, so he took it like a champ! I want to know how you guys took it. Hopefully tomorrow she doesn't cry.
