My little boy had his 3rd jabs today and his temperature is higher than usual but below 37.5. I normally put him to bed in socks, a long sleeved vest, a long sleep suit and his sleeping bag. I'm worried incase his temperature rises through the night and he gets too warm so I've put him in a short vest, long sleep suit, no socks and I was going to put a blanket over him but he'll likely kick it off. Is this okay or should I just dress him as usual?
