i kno babies do different things at different rates, but... melissa is soooooo close to crawling, altho i think shes early. (she shuffles her bum in the air and moves her arms forward, she can crawl a few centimetres lol not really crawling yet but shes really going for it and i can see progress) but, she shows no signs of tryna sit up. should she be by now? when on her back she wont raise her head at all. actually she wont stay on her back for long, she rolls onto her front then lifts her head and shoulders (like a "cobra" yoga position!) so she seems much stronger on her front, hence the early crawling. ought i be helping her practise, by sitting opposite her and pulling her up by her arms? coz i never do this or maybe i should sit her on my lap, and move my hands away from supporting her so theyre just near her ready to catch her balance? or dont i need to do anything but leave her til shes ready?
