How to swaddle a 4 year old

Make sure you have a VERY large blanket.

My middle daughter decided to see what it was like to swaddle a 4 year old. She is convinced it's the only way she will ever be able to get our 4 month old grandson to sleep.
I told her to try it on her brother, to see how many very large swaddles she would be needing later on.
She decided it's alot of work and they just wont stay in the thing.
I guess she'll have to figure out another way to get him to sleep in the next few years.
