Hi all, 6 month old DS was getting better at sleeping, but his current new development is to wake at 3.15 on the dot and then just not settle back down. He is still awake an hour and a half later, not crying but talking/shouting and wriggling around. I fed him initially but it's not helping. He self settles at bedtime and at nap time, he learnt to roll over yesterday, and think he's wriggling a lot in his cot. Could this be it? Any tips greatly appreciated. My DH is getting up for work in 20 mins and I've been awake since 3.15. Am going to be a wreck tomorrow.
