My son is 12 months old and cannot sit up unaided. We have seen the pediatrician who sent our baby for blood tests to check for a chromosome disorder. I am in my 40's. I confirmed that my baby hasn't downsyndrome or muscular dystrophy. So, we are not sure what he has. Is there any one with a baby like mine who can't crawl or sit up at 1yr old? He eats well, his weight is normal. He also sleeps well and apart from colds and coughs now and then, he is healthy. Any suggestions about what I should do now?
My granddaughter is one now, but still not sitting up unaided. There were complications during pregnancy. The baby does not try to sit up on her own, crawl, or try to pull herself up. Even when I hold her up, she doesn't put weight on her legs. Should I be concerned? What do you propose I do now?
