No real advice here either as nothing worked on our daughter aside from long drives or walks in the park. We tried everything. She’s 8 now and often says sleep is boring as you can’t do anything. She’s just very, very active.
What I will say though is whatever you do, find time for you and the Mrs. Sleep deprivation will put your relationship under massive pressure as you won’t think straight. It’s horrible but normal. My mum turned up with a chicken casserole one day and took our daughter out for a few hours. We ate then slept. It was amazing.
