DS is 1 and I want to start introducing a pillow so have been putting a fairly flat cushion in his cot when he goes down for naps. The problem is he has a sleeping bag so doesn't have a designated head end, at the moment he's asleep with his feet on the cushion instead.Should I leave it until he starts staying in one place or persevering? Also I want to get him his own pillow but (stupid question) do I just get him a normal one or are there special kids ones?
