Sleep advice needed!

Cassandra

We recently took the dummy away from my lb and there were no issues but now he is having trouble falling asleep (pretty much the only time we used the dummy) He cries and performs for ages until he's absolutely exhausted. I've started dreading his nap and bed times because I know it's going to be a warzone.

I think he still needs something to help soothe him to sleep but I tried a lovey toy, the dummy again, and nothing is working. He plays with it for a few minutes then goes right back to crying. Does anyone have any advice to share?
