So my LO is 8 months old. Shes sat well since 6 month old, no support needed. She rolls both ways really well and for the past 2 weeks she has been crawling on her arms and sometimes goes onto all 4s and rocks. However my concern is if shes on her bum and a toy is out of reach she will open her legs and try to reach for it but wont go into her knees like most babies do also when she stands its like her knees keep on giving way, so now I'm worried she might have hypermobility and low muscle tone.
I know shes only 8 months and I shouldn't compare her to others but this does worry me. Shes been trying to crawl now for nearly a week.
