Not sure I’ll be much help but I’ve struggled on and off with my now 3 yr old and ewu's. They seemed bad at first but looking back at least when she still napped we could catch her up a little. Now she doesn’t we just opt for an earlyish bedtime, but not too early to completely mess up everything and encourage ewu’s
It really is mind boggling and very draining and although people say you’re not alone and we know there are other children out there doing the same, it still feels pants when it’s happening to you.
We’re in the middle of our latest bedtime issues and now we’ve got a chest infection so sleep is off again. Although she has been brighter she is now playing us to sleep in our bed as we allowed her when she was coughing so bad at the weekend!!
I also noticed that my littly always has sleep probs leading up to clock changes, whether that means anything who knows, but so far we’ve always just ridden the storm and stuck to the new time, give or take 15-30 mins to help keep ot at bay.
To add insult to injury, I have anxiety and sleep is my trigger so you can imagine what I’m like right now
If it’s any consolation, my now 4.5yr old nephew was a nightmare until he was almost 4 and now most days my brother and his wife have to wake him!! Oh the bliss of a lie in til 7 would be amazing, or 6 would be great right now
