I don't remember the other kids being this much fun around 18 months---except maybe Munchkin! Squirt is definitely her own person, breaking all the rules the other three set. Hubby took her to Nursery yesterday and she loved it.
She just wants to be one of the big kids. She wanders to the playroom all the time and will just sit and watch the kids play. She is so mellow--when she's not teething. She's so fun!
