My DD was exactly like this BUT she was pretty much crawling before sitting so that's that theory gone!

I think it's because I'd always put her on the floor on her back or her tummy so I wasn't really teaching her how to sit and it wasn't until I went to Mothers Group and saw the other babies sitting that it even occurred to me! Whoopsy!

So I tried to encourage her very gently. At first just for a few seconds with me with my hands at the ready. Then I'd try again a bit later in the day but not try too many times.

She got it after a few days; a week tops.

So no harm in giving it a go, I reckon, but no point pushing it either. She'll do it in her own time.

I wouldn't worry about the conflicting advice - just do what you think is right.

My current MCHN is fabulous but her off-sider's a shocker. Always quoting this theory and that theory. She tried telling me when DD was a couple of months old that she needed 20 minutes of tummy time each day or she would never learn to roll. Well, DD hated tummy time so I stopped doing it at all. And what d'you know, she was one of the first rollers in Mothers Group so I take all this stuff with a pinch of salt now.
