With my big ole belly up against my husband's back (sometimes I use him like a body pillow when he sleeps, it's comfortable, don't judge) ANYWAY, it's like she knows he's there cause she starts kicking real hard. So I'll roll away and she quits, roll back to him and she starts all over again... It's like a game. Lol, she works out and I get a giggle out of it, it's win/win... .
