WHAT?? what a load of ballony!!!! lol sorry. But how many 8 month olds can hold them self up!? That CHN has no clue. Neither of my kids could hold their weight at 8 months. Neither does any of my gf's kids. DD cant still hold her weight now. But she is meeting her milestones, as did DS.
Hmmm i seriously would not worry one bit about that. If an 8 month old is holding their weight then i would say they are quite advanced. If she isnt doing it by about 18 months then maybe that would be something to look into but i think thats just added stress and worry that is really unnessesary hun.
