Sounds like a healthy weight for baby at this stage
Well I know I personally was born a month early, so that's... Like 36 weeks or so, and I weighted 4 LBs 9 oz, so to Me sounds very healthy :)
I'm no expert, but I believe your baby gains up to .5 lbs each week past 34-36. Plus you have 4-6 more weeks of growing before that. You should have no worries about weight. Sounds totally normal.
I had one yesterday as well I'm 30 weeks n my boy is at 4 pounds 2 ounces and has lots of hair!!! She said he's healthy a lil bigger than most but not abnormally big
