Yah they gain a lot towards the end

how can you find out how much your baby weighs?? sorry if that's a dumb question... ftm and have no clue about anything other than what my doc tells me

Yes that's normal. My baby came at 24 weeks and she was 1lb 4 ounces.@kaydentaylor01,

mine was only ten oz at 20 weeks. you may just have a small baby but he could always gain a lot towards the end.

Oh I was a bit nervous

It is normal, he's just going to be a skinny baby . Or probably he/she will gain weight in this coming weeks. Don't worry, I have 25 weeks and 3 days and my baby is also 1lb , my daughters were 5lb when they were born and they were full term, so it's normal
