Which one is your LO, and what about your older kids (if you have them?) (I think all of the younger kids on the board are still pretty young to tell).
The girls are VERY shy. Especially Brooke. It takes them a while to warm up to a new situation. Brooke likes to say she has to go potty to get out of a new situation. They are not the kids in the store that are saying hi to everyone they see. I often wonder if this is normal. They are fine at daycare, but then they are with those kids/teachers 4 days a week, so it's not like it's a new situation.
