Kayla is four months old!

It is hard to believe Kayla is already four months old! She had her check-up yesterday and was 13lbs 14oz and 23.75 inches. Our doctor just loves babies, we go to a family doctor so he doesn't see many babies throughout the day. Usually he tells me "she's just perfect", but yesterday he said she was advanced. He mainly said this because she is very alert and watches everything. I of course think it's because she has to look out for her big brother. For example, yesterday I had laid her next to me on the couch just to let her stretch. Jack came over and tried to roll her off the couch onto the floor, all the while saying "thank you". He is such a polite little boy...
