My son was born 9lbs even on November 26th, he is now 14 lbs not even 2 months later. He's in 6 month clothing. He is also ebf no formula no nothing just my milk. DH mom is always making comments about it ugh.
I've always seen EBF babies to gain more weight at first and then even out. I think you are fine since you are EBFing! My son was 9lbs 6oz at birth and he was eBF for 2 1/2 months then formula and at his 12 month he was only 20lbs! Everyone thought he'd be huge because of his birth weight lol
My son was born 10/11/12 and weighed 9lbs 6oz and on 12/7/12 he weighed 14 lbs.. I feed him according to what doctor recommends.. Babies gain at different pace so don't worry when the LO gets moving he will lose weight and not gain so fast
