Im son use to push on my rib cage it to be very hard for me to breath but that was because he was to big for my tummy
Some people are ignorant. Don't listen to everyone
My son LOVE hanging out in my rib cage and rolling in it. But I don't have any broken ribs. I mean yeah it's possible for them to break/bruise one or so and it's VERY painful for them to play in. But the girl telling your sister that is wrong.. It's very rare that they break their moms rib bones.
thats not true both of my girls have never even touched my ribs.. i do know of girls that say it hurts really bad n one that bcz of her height status n body frame baby did actually bruise or broke her rib but shes the only person i knoe, besides that i dont think that girl knows wat shes saying!
