DS1 used to. Between the baby years and up until he was about 5 or 6.
DS3 (now 3) seems to be the same.
For example, put him to bed last night as normal. About 11ish he called out for me and was absolutely roasting. Took his temperature and it was over 40 (I actually thought it was going to be higher from the feel of him). Dosed him up with nurofen. His temp came down after about an hour and he slept soundly in with me. Right as rain this morning.
