Olivia, ak, n rabbitz,
Dont worry too much abt e est wt of bb ok? Its really just an estimate. For my #2, estimated during week 39 was 2.9 but when i delivered e same same, bb was 3.6kg. Thats how off it can be. Size of mummy n bb is one thing, but also depends on yr pelvic shape n head circumference of bb. I wld encourage 1st time mummies to.try natural really. Coz if not for #2 or #3, u might not get a choice. Some gynaes r not v pro VBAC. I also had a friend who.had been thru both-natural w/o epidural n c sec w GA. She said natural recovery definitely faster. I myself is v small-44kg pre preg. But 3.6 kg bb was no prob.
Moments-hope things turn out well. Third time mummy already, but do take care of yrself n watch out for. Post natal hormones... U sound really worried. Let it go to yr hb to handle if nec ok? U need to.recover fr e birthing too.
