... Isn't rolling, crawling, cruising or making any attempt whatsoever at moving! She just sits like a little Buddha. She cries when on her tum & hasn't learnt that she can just roll onto her back if she doesn't like it! She's been sitting in her own since 5.5 months, she clapped from 6 months, could feed herself with a spoon from 6 months. She is a chubba bubba & stands well (when propped up or held). Should I be concerned? Mostly I'm worried at lack of rolling!?! She did it a few times at 6 months but then cried when stuck on her tum. Anyone else the same?
