Does anyone use this blanket? We use it consistently for all naps and night time sleep, he is 11 weeks old. My mother criticizes me and says it's putting my LO in a straight jacket and says it will hinder his development. I am worried about that too but my LO will not stay asleep without it as his arms are flailing and his jolts wake him up. He is a light sleeper. Another thing is on the package of the Miracle Blanket it says not to use it for more than 8 consistent hours, or 10 hours in a 24 hour period. Well...since he sleeps for 6 straight hours, then is fed and sleeps another 2 then fed and 2 again and most of the time I keep him wrapped unless I have to change his diaper in which case I unwrap the blanket change his diaper and wrap him right back up again, I am obviously breaking the rules. ALso because he sleeps in it for all naps we are going way over the 10 hour limit. But if I simply swaddle him in a recieving blanket or even a swaddle me blacket with velcro he busts out of those things in under a minute. Am I hurting him or his development by using this Miracle Blanket? Why does it have an hour limit on there? Do his arms fall asleep, because when I unwrap him when he wakes up he seems to be in a little pain... What should I do instead if I can't use this miracle blanket for those many hours? Should I not be swaddling for naps? When shoudl I stop swaddling?
