Yes she is, my little girl is 4 months old. I can't believe it. Where has the time gone. She can "talk", well screech like a terradactyl. She can sit up in her Bumbo. She grabs and holds on to her toys. She knows who Mama and Daddy are and looks at us when we are talking. She has started to giggle when we play with her. She is now in her own crib in her room. That was a hard one for me, but I'm doing well with it. It's a good thing too, because now she is rolling over. She loves tummy time. When ever I go into her room to feed her she is perpendicular to how I lay her down and is usually on her stomach.
