OK quick update, he only had 1 nap at nursery as expected so he was in bed by 6.30pm. He then woke at 3.30am and self settled, woke at 4.30 am self settled again, woke at 5am, hadn't settled after 5 mins so I went in and did PD he resettled and then woke at 5.30am, did the PD again and settled until 6am. Drove him to nursery and he fell asleep in the car for 30 mins. Am I doing this right or am I missing something somewhere?
