My girls are sooo different from eachother. Fatty will eat 5 oz and is hungry every 3 hours still. Skinny is still a 3 oz feeder every 3 hours. She's 12 weeks and still the size of some newborns! They do sleep longer stretches at night so that's nice. They were in different size diapers and are coming close to being in different size clothes (as Fatty out grows the 3 month size). All my cute matching outfits won't get worn! They're healthy though but definately different. Anyone else?
