Interesting Find

I have an online tracker that I use to enter in the girl's height/weight up to 2 years (and then I printed off Hannah's for her baby book). I found something interesting as I was entering Hailey's height and weight for 3 months. Hailey is the same size as Hannah was, except she is a month "ahead". For instance, Hailey is around 14lbs and 25 inches at 3 months. Hannah was that same size, but at 4 months. Although I have said from the beginning that they look a lot alike to me, it's interesting to see that they are proportioned the same.
