DD 2 is one (yay) tomorrow, she was rolling both ways from about 4-5 months and DH and I have just noticed recently say last six weeks she doesn't do it any more.
If you leave her on her back after changing her nappy etc she just lays there will swing her legs up in the air from her hips but will not roll to her tummy.
What usually happens is we change her dump nappy and on way past while doing a million other things just sit her up so it seems she has lost the skill.
She sits well, is cruising furniture well and stands alone for a few seconds regularly.
Do we need to worry or look into this?
