Baby has to be head down. I'm 38 weeks and 6 days now, my baby has been head down this entire time. So I understand your concern for the baby moving by the time you deliver. I just kept asking my doctor if the baby was head down. Lol. Sounds silly but I can't really feel for myself and I DON"T want to end up having a C-section at the last minute. Hope this helps...
Once they go head down they tend to stay that way.
