Ok, now you mention it he had 11hr30 night last night compared to 10hr30 the last few days! We put him to bed at 1800 because he only had the one nap yesterday and even that was after a 5hr15A! He woke at 0440 but was back asleep at 0510 after a bottle. He then WU at 0600.
So what shall I do from here? His nights are always varied. We always aim for 1900 BT but it depends how the naps have gone and WU time.
Thanks
