My son is 13 lbs at 5 months. I'm sure she's fine. Doctor would have said otherwise. She's just small like my son. My dr said as long as baby is following growth curve all is well nonmatter if 90% or 2%. lol

As long as he's on the charts.

she is three months

10.4 pounds

What's she weigh?

no, my son is the same way. I think he's like 2 or 5% but he's growing as he should be so it's no concern.
