My DS has started having a lay in lately - he will go down at 8pm, and wake at least twice in the night for an ounce of milk here and there (only wakes for maybe 10 mins). Then hes up at 7.30, has a full feed and then goes down again until 10! He used to stay up from 7.30!
He has just learned rolling and is starting to make moves towards crawling, so could this lay in be related to that? The amount and quality of his daytime naps havent been affected at all.
