I started to lumps sticking out of my bump from around 32 weeks. Not obvious what they are without a good feel though. Sometimes they are definately feet, othertimes knees judging by the shape. Don't see or feel hands as baby is head down, just get tickled and scratched.
Baby sometimes reacts to being prodded by prodding back... sweet
I am 27 weeks and if I am laying down relaxing normally after a days work its like the baby is doing a rumba around my tummy. DH loves it and watching the baby react to our voices is really funny if its just the two of us and Im am moaning about work or something like and we are really debating its like the baby has something to say too. I can't wait to be able to get a responses
Was just wondering whether it depends on the baby's position, as Ds was LOA until very near the end then sort of slipped round sideways a bit OP. If they are LOA, then I think feet and hands are pointing towards your back so might not show, maybe they would if baby was lying breech or OP???
