this sounds a bit odd, he is my 2nd born (ds is 10) and ive always felt something was off with his development/cognitive skills. But, he doesnt 'try' and walk. You know how a baby will almost instinctively move their feet back and fourth when an adult supports them to do so? he cant/doesnt/wont do it. He can weight bare although doesnt do so for long periods, and he loves jumping. Is this normal? Im sure my other son used to walk with me long before he ever even tried to walk? Its like he doesnt know how to move his legs/feet or that it equates to walking? thank you!
