So I'm exactly 4months pregnant as of tomorrow. I have a small belly at this point but I'm wondering should I stop my cat n dog(10pound jack russle) from laying on me? My cat likes to curl up more towards my chest when we are watching a movie. An my dog like to lay ontop of my legs but plops her but on my belly/pelvic area. Can they actually do any harm? Or are they small enough that it's not a huge deal. I mean even my husband lays his head on my belly sometimes lol
