19 mo ds has never been the greatest sleeper and used to wake at 5 every morning. However in past few months this has improved and he wakes around half 6. Until the past week that is!! Suddenly getting earlier again. Could it be that he has a nap too late? Yesterday it was 2 until half 3 nap time. Is this too late and affecting wake up time? Or am I clutching at straws? If this is the case, how do I make him nap earlier? It was a battle to go down yesterday even tho he was hanging!!
