My 16 mo DS has suddenly started needing to be settled off to sleep again having been great at settling himself off. He has always woken in the night - have usually suspected windy tum as usually does a big fart after a while!! But lately he wakes and seems to suddenly start crying and is standing up in his cot waiting for me when I get into his room. I wondered whether he has started to become afraid of the dark, is he too young for this? Just occurred that when he wakes too early i.e 5.30 like he did this morning, he just babbles himself off back to sleep (if I'm lucky!!) whereas when it is dark he seems to need me to go through to him. Any advice greatly appreciated!
