With ds I did tummy time every day from birth a few times a day, gradually building up in duration. He rolled early and then went on to crawl and walk early.
Am pregnant with my second baby and I'm wondering how essential tummy time is. I don't want an early crawler/walker (didn't realise the implications of this with ds obviously) so I was wondering if there are others out there who didn't do any at all or who only did it occasionally it or when it occurred naturally.
