Sorry no tips, but my son is 6months and we are in the same boat! I contacted the company they said to try and double up on sleepers to make it seem like they were wearing it still, that tight/swaddle feel, but didn't work for me!
My lo is 6 months old. We just weaned from Merlin. It took 1 hard night but now he is sleeping better. We had joked right before weaning that Merlin was starting to lose his magic. Now heis in a sleep sack and much happier sleeping on his side and tummy.
We went cold turkey and did CIO and sleepsuit weaning all at once. It took 3 nights but my girls now sleep 11-13 hrs without the suit, without waking overnight and they sleep on their bellies. They were just over 6 mos when we did it.
We welcomed our girls on 11.7.12 @ 40w0d!

No help here We tried breaking DS of the sleep suit a week or so ago. It didn't go over so well and we are currently back in the suit. Problem with him is he gets very frustrated when he rolls onto his tummy so when this happened without the suit he would freak out. I felt like it was ruining the sleep training we started a month ago. We are going to wait until he is a little more mobile so he can get himself into a preferred position before we try again
