He is currently asleep on his front , with dummy in which I can see him sucking. I'm worried his head is getting too flat. He goes mad after 5 mins tummy time so I thought if I watch him during his daytime naps his head might get a rest on the flat bit. I have a huge sofa with a huge stool thing pushed up so he is safe and I can watch him.
Also when he was newborn he used to sleep on his tummy vertically on my front so that was on his front too, he is 15 weeks now.
