Our 17mo ds has never been a fantastic sleeper but lately the nights have become a battle. He doesn't want to go to sleep but when we eventually succeed he'll sleep for about 30 mins and then wake like it's the morning. He's clearly physically shattered but it's like he can't shut his brain off. Apart from last night when he slept for 7 hours he's been waking 5 - 8 times a night ... and that's when he's FINALLY crashed completely at about midnight. He's had odd phases before, when he's been on the cusp of doing something new, and at the moment he's learning words at a rapid rate. Currently 75 words to his vocab and counting. Maybe he's frustrated at not being able to talk properly? Has anybody had something similar with their toddler? Our doctor only advised giving him calpol or similar to knock him out a bit. Any advice or suggestions greatly appreciated!
