DS is nearly 9 months and had been sitting unsupported for about 3 months well, but in the last week or so he has been putting himself onto his stomach, im not worried as i just leave him as hies usually playing and just pick his up back into sitting when he eventually cries because he wants to sit. Does anyone elses baby do this and does anyone know why is it that he wants to get down on his front to crawl??? He had never liked it on his front before and every time i tried putting him on his front he screams. he cant roll so doesnt like to be on his back either. like i said im not worried that hes started doing it just wonering if anyone elses ds/ddd does it and why
