She's holding up four fingers over the 3 because she was definitely closer to four months old than three months when we took the picture. Children always have a way of telling the truth and throwing us under the bus no matter how young they are.
Anyway, our sweet little girl is growing up so quickly. Honestly I can't remember what all she was doing at this age but I do know that it was super cute. I'm pretty sure she was babbling, socially smiling, grabbing at toys and being the added ray of light that her mother needed each day.
