Husband and Baby belly

Candice
So let me start off by saying my husband is excited about us expecting a baby. I'm currently 24 weeks and he has felt baby move a few times but the only way he really talks/ touches my baby bump is if I put his hand on it or ask him to talk to her. When he does it's very brief. 
I'm not sure if he just does not feel a connection to her yet. We have had some complications with this pregnancy and I'm considered high risk. So he is worried about me but I'm not sure he is so concerned about her.. Maybe he is worried about building a connection to her with a possibility of losing her.. I'm just not sure. I do love my husband and he will be a great father I'm just kind of confused on his feelings about the pregnancy so far. 
Anyone else having similar experience with the way your SO acts towards your unborn?
