Good luck with the wedge LouLou.

They will not want to be wrapped forever and you'll know when that happens because they'll wriggle out before your very eyes and smile at you with pride.

I still partially wrap Ella as its a very powerful sleep cue for her. She also has a dummy and by 5.5months she had control of it and could pop it back in. Try unwrapping one arm during day naps so he gets use to pulling the dummy out and popping it back in. You might need to help him do it a few times.

Good luck
