Is it normal?

I'm 19 weeks and my little one is always on the move and loves my left side.But when their ( don't know the gender till thrusday) daddy puts his hand on my belly, the baby always moves right under it and it feels like he or she is pressing into his hand! I think the baby might like the warmth my husband gives them because I'm constantly freezing. But does anyone else's baby do this. We are laying in bed, my husband is asleep with his hand on my belly, I thought the baby was asleep until he moved under and is kinda rubbing against his hand!
