When we transferred Aidyn to his big bed, we spent nearly a month of nights lying on the cot mattress on the floor next to his bed until he fell asleep.

Then after those few weeks, we stopped staying on the floor, but he still kept coming out, so we would just repeatedly put him back into his bed... over and over. It took about two weeks, and then all of a sudden he learnt to self settle - he still comes out maybe 3 or 4 times - but it is a HUGE difference compared to coming out 20 or 30 times like he previously had been!

Goodluck!
