I just had my fourth girl 6 days ago. 7lbs 4oz she was born at 37 weeks 4days so a bit earlier then my other 3

I’m nursing (which isn’t my first time I nursed all 3 kids). We’ve been to the doctor twice since she’s been born and she’s still not gaining weight. She’s weighing in at 6lbs 11oz today. Doctor is not crazy concerned but it concerned me. My milk is in, she feds every 2-4hrs (sleeps longer at night), lots of wet poopy diapers.

I’m assuming since she was a bit early that shes just more sleepy and is taking longer to put on the lbs.

Anyone else have any similar situations should I be concerned?

She’s not fussy, she’s not dehydrated, skin color looks great I can’t complain she’s a pretty easy baby thus far.
