When Liam was a tiny newborn I had a favourite blanket I would use for him. It was a light blue cellular blanket and it went everywhere with him. I would put it over him in the pram when we were out and about, sitting in his bouncy chair or even when he had a nap. When Sophie came along she had the same blanket but in pink. The blankets would get washed 4 times a week. I always thought washing them often would help stop bacteria and germs.
