aww bless you, i really wouldnt worry, everyone is different, before i had my first i wasnt a kids person at all! i found them annoying and never even thought of having my own, but the minute she started kicking i was like.... wow i little person in there and just grew attacthed!
im 33 weeks now and i must admit i have named her and i talk to her daily updating her on what is going on lol but everyone is different but yes there is a huge connection when you give birth it is quite amazing,
but some people dont feel it straight away, you have just been though a mega amount of pain, your tired, probabilly frustrated.
if you are really worred try talking to him/her, sounds crazy i know but it really feels like your getting to know them
or get your partner to, my baby always seemed to kick more when my partner lies his head on my belly and talks to her its really sweet,
but seriously dont worry, if you worry about it too much you will just cause yourself unnessesary stress.
And when you bring her home and she starts to form into a little you, you will look back and wonder what you worried about!
good luck xx
