I really want some reassuring that he/she is growing nicely according to plan
Susan_22 - Having a third tri ultrasound will only make you more anxious then! Scans in the third trimester are very innacurate for size, as you need to remember, their machines work on mathematics calculating averages, but in the third trimester, baby's own unique genes take over and will likely be bigger or smaller than those computer averages. People come in all shapes and sizes, as do healthy babies, so it's important not to get worried about size in the third trimester unless there is an underlying medical condition effecting baby's health.
