Our DS was poorly in the night. He woke 4 times but settled back down easily each time. He had a temperature so gave calpol, once at 11am and then again at 4am. He is still asleep and it's 1pm. My natural reaction is that the sleep will do him good, and he is sleeping contentedly. As time goes on though, I am getting a bit worried and wondering whether I should wake him up. Any thoughts?
