Any advice ?

Alright , I'm pretty sure I'm pregnant . But I have a 7 month old little boy . He is all knees and elbows . Nothing gentle about him he is ALL boy . And he is very very rough . When I hold him he has no clue how to be still (and of course he doesn't understand ) but he's always kicking me or digging his knees into my stomach or lower abdominal area.  Do any if you moms with young ones have any advice in how to prevent that ??
