My 13 month old DS has been restless all day. Put him down for his lunchtime nap and after 30 mins he was crying hysterically. He normally sleeps for an hour and a half. Couldn't calm him at all. He went down at normal time tonight but has been awake every half an hour crying hysterically and it takes ages to calm him only for him to wake up 30 mins later. He doesn't have a temperature but is quite sweaty. Have stripped him off and given him some water and have just got him back down. I gave him some Calpol at 5.30 so can't give him some more for another half an hour. We think he may have a tooth coming but he's not been like this with any of his others. Any advice or suggestions greatly appreciated!
