2 month checkup-little peanut!

Angela
Top photo my daughter Alexa (younger) & bottom photo my son Kennex (older). Both pics at 2 months old. 
My kids are 13 months apart (boy then girl). They were both born the exact same height and weight (19.75inches, 6lb 14oz). Both exclusively formula fed from day 1. At 2 months, they both clocked in at 22.75inches... My son however was 11lb 14oz and my daughter is exactly 10lb even though, by volume, she's eating more per feeding and per day than he did haha. Anybody else have boy/girl siblings that you're having fun comparing??? 😌
