When my Daughter was born everything said do not let the baby lay on their side or tummy. I tried hard but she turned to her side every time you put her down. If she was on her back she would wake and cry. I spoke to my mum and she said when I was a baby I slept on my tummy, as did my brother and sister. None of us slept on our side or back. We just made sure we bought a breathable mattress so if she ended up face down she could breath. Now she’s almost 1 and sleeps however she feels. Which is usually cuddled up against me while I feel stressed all night.
