I was trying for a vbac and they tried to get me to book in at 8 days over, which was totally convenient for them! I pushed quite a bit as I didn't want a c/s and ended up going 14 days over and having an elective on a Saturday morning which was a bit unheard of. I would think that shifting the date one day here or there to suit you is totally fine and the babysitting issue is definitely something to consider. It can't hurt to speak to him at your next app xoxoxo
