Hi, My ds2 is 1 in afew weeks. He is a very happy contented little boy who is extremely laid back and a joy to be around. He isn't crawling yet, although he gets everywhere by pulling himself along the oor with his arms and pushing with his feet. he may just continue to do this instead of the usual way of crawling. He cant sit up unaided, well he can for a ceratin amount of time, upto maybe a minute or so. i definetely wouldnt be able to sit him down and walk away from him. He has started ping himself up on things that are low to the ground. he does have quite lot of strength in his legs and will stand just holding my hands. He sits upright in highchair and push chair but obviously he is supported. i am really starting to worry now as i thought he'd be able to sit better by now. its almost ke he has no interest in sitting cause he wants to be off doing something else so its like he hasnt learnt to do it, does that make sense. any advice please xxx
