I can't believe that M is four months old already! She is such a chunker, it's so different from when C was a baby. Even now, his clothes size matches up with his age, but M is already in 9 month clothes! She is 17 lbs and 4 oz, which is the average weight of a baby over 7 months old! She just needs more room to fit all of her cuteness in. Don't believe me? Check it out for yoruself!
