My little girl is 7 months, I saw a family member stand her up only holding her hands as she wobbled and struggled to stay up. I said "omg" the same moment her legs gave way and she fell. Me, my partner and all my family do this but support her under her bum or under her arms to let her bounce and kick around, weve never let her hold her entire body weight. This is my first baby so I have no idea if its dangerous or not, does it put pressure on her knees and bones or is it a good way to develop blance and muscle?
