Hi I'm just wondering does this happen to anyone elses baby, when my DS is sleeping at night I will feel his chest belly and back of neck and he could feel really cold , then I will go get him a vest to put under his baby grow and when I get back he feels warm again, this goes on all night one minute he feels freezing the next minute he feels like a perfect temperature, our room is warm with a fan going at the other side of the room not facing him and he just sleeps in a sleep suit and folded cellular blanket, im not really sure what to do
