When I was researching torticollis and flat head etc I found a website that said a baby should spend half the day on their tummy. Ella's never spent nearly this amount of time. With the next baby I will make sure that I get them used to tummy time from the beginning, but I was quite shocked at how much tummy time they need to avoid things like flat head etc. Wish the HV's stressed how important it is, especially as it could have really helped with Ella's tight neck muscles at the beginning.
