My first child with paws loves belly

He didn't really start cuddling it till it became large, about 30 weeks. But the most beautiful thing about it is, everytime he cuddles my belly she immediately starts kicking and reacting to him. It's the only SURE way to get her to respond and it works almost instantly. But don't be fooled, he is not the type of cat that loves everyone. He doesn't like kids and he's content with just mine and dad's affection, he'll take a pet or 2 from a stranger but then he's off on his own. But I'm hoping he loves her since it'll be his baby sister. Maybe she'll be an exception
