Im having a boy. Went to ultrasound at 36wks 4days and the baby is only 4.11lbs but he gained 10ounces from the last weight check at 33 weeks. They said they might induce me at 37 wks if they saw any problm. Went to my ultrasound 37wks 4days and they said everuthing's good with my baby. But they didnt check the weight and they will next week on my 38wks 4days. Is it normal that some baby's are small? That's the doctor's only concern. Baby being small. But everything is fine with him. Me & my husband were tall tho i was only 5.2lbs when i was born
