My DS is only 2 months and I'm still wrapping him, though he does not liked his arms being too restricted, and would wiggle and complain untill he got his hands free.

I know alot of babies like to sleep with their arms above their heads.. being wrapped restricts that.
There is a way to wrap so they can have their arms above their heads.
You need to have a larger square wrap, the bamboo ones are good, I know these as musllin wraps. Lay it on a flat surface and fold down one corner, position your babies neck in the centre of the fold. You should have 'pockets' for each hand. Slip one hand into the pocket, then wrap the end across baby and under his/her back, repeat with other side. Splay the mateiral(sp) at foot end, bring it up and behind baby. Your baby will now still be wrapped but have more arm movement.

My DS has taken to this kind of wrapping at night. During the day my DS does not like to go down, but is happy to sleep while on the move, so I just go about my daily activites, DS sleeps in the car, in the baby sling or in the pram therefore generally unwrapped. If I put him down during the day, I find he sleeps better on his tummy, so he does not get wrapped, that way he can lift his head if he needs to. I also have him in the pram so he is never out of my sight.
