We are adopting a LO who will be approx. 11 months when he comes to live with us. His foster carer has said she has tried to do tummy time with him for months but that he's just not having any of it. The social worker said we should look into what impact this might have on him and what we could do about it. I've read up on all the theory as to why it's important but there is little about starting it at a later age or what can be done to prevent health issues. I'm worried about his neck in particular, though he is sitting by himself fine and bum shuffling. Am I right to worry? Anything we can do at this age to counteract a lack of tummy time early on?
