Aww tiny baby I just had boy/girl twins almost 4 months ago and my daughter weighed just 3lbs 15oz so I wasn't able to put this on her. Now she's too big for it.
Ours are boy/ girl twins and he was borne first at 2 lbs.. We had no idea there was two and the little mother let out a yelp and the Dr said OMG there's another one and it's stuck so she delivered emergency c section ay 1 1/2 lbs. but they seem to be doing good. Congratulations on your new babies.
