Swaddling

I have been swaddling my son since he was born. I currently bought the Miracle Blanket and LOVE it ! He is 3 months old and sleeps really well. He'll sleep from 8pm till 3am-4am, then get to eat, then go back to sleep until 7:30-8:00am. Recently though, he has been getting irritated with the swaddle though and is trying to bust out of it at night. Is there any age that you shouldn't swaddle them anymore? For anyone that swaddled their baby- when did you stop swaddling, and did your child wake more in the night once they weren't swaddled anymore?

Thanks!

My daughter just turned 3 mos, and I use the Miracle Blanket every night and for naps. She sleeps AWESOME! She goes to sleep around 10pm and gets up about 6:30-7.
I think that swaddling is most helpful when they're really little because they still don't have control of their limbs and often jerk themselves awake or smack themselves in the head , but I think aroound this age they are more controlled so I'd say if he doesn't like it, try naps without swaddling and see how he does.

Good luck!
