Thank you for your reassuring messages
It hasn't gone well though. As soon as he does a decent/normal night, things get out of whack.
First off, he couldn't settle for nap til 2pm. Then woke crying half way through. I re-settled.
Then at BT was seriously UT and took ages with lots of upset. Eventually he was asleep by 7.40pm.
In the last two weeks, he's had two days with just over 12hours sleep total. The following night (or two) have been horribly short as a result with EWs (9.5hrs and 8hr45).
What will I do if this pattern repeats itself tonight?
