E is 9 months tomorrow and still wobbly to sit up, she can do it for a few seconds but ultimately always falls. I keep getting told all babies hit these milestones at different times but I can't help feeling a bit sad that I know I won't be seeing her take a step or stand before I'm back at work because she doesn't properly put weight on her feet and seems to have no stability in her back iykwim? She can do a sort of sluggy army crawl so she's getting somewhere but I'm still worried. Has anyone else's lo been quite slow to get the hang of sitting? Did they suddenly just surprise you one day? My worry is that she has a sacral dimple and worse case scenario it could be an underlying problem, but the hospital say she's too old for an ultrasound and I don't want her having an MRI unless necessary. Every time I ask a HV or GP they won't give me an answer as to wether she is just going to be a slow sitter or if its a potential worry.
