Baby's Magic Tea Magic Merlin Sleepsuit

"5.0 out of 5 stars" - UPDATE (3/02/13):we finally retired the sleepsuit last week. our son is now 6 mos. old, is 19 lbs. and 28 inches long. he still fits fine in the suit (though the sleeves are a tad short), but we decided to move him out of the suit because he's very active and we found him on his stomach a few times already. so yes, it is possible to roll over in the suit...and we just thought it was time for him to learn how to sleep without it. amazingly, our son sleeps pretty well without it. we have him in a full body jumper and a sleepsack...what's amazing is how much he loves to move around in his crib...he travels a lot...and he loves sleeping on his stomach, which is fine at this age. the sleepsuit served us well, though, and it was the perfect thing for him from 3-6 mos...hope it works for your kid.UPDATE (1/22/13):our son still sleeps in the suit and still does well in it. he sleeps anywhere from 6-9 hours through the night...and he seems to like getting into his suit. at 4 months he started rolling over...and the suit prevented him from rolling over while sleeping, but last week we found him on his side and then on his stomach while wearing the suit (at 4.5 months). so it prevents him from rolling easily, but not completely. we've since put a couple of pillows on either side of his legs and this has prevented him from rolling...he is now 5 months old, about 18 lbs., and about 27 inches tall. he fits the suit perfectly...we've washed the suit a few times, mostly when he's had a leaky diaper overnight. just turn it inside out, wash regular, and dry. no big deal. hope this helps.ORIGINAL:some tidbits:- my son is 3-1/2 months- weighs about 15.5 lbs.- is very active; always moving his legs and arms and rarely sits or lies still- i don't think he'll fit into the 3-6 mos. when he's 6 mos...but it's a bit loose on him right now.- we live in hawaii and it's not too hot to put him in it with just a diaper. he never seems sweaty or over-heated. he'd wake up if he were. swaddling actually made him really hot.okay. my son was outgrowing his swaddle me and we were thinking about what we should do next. he still startles quite often and moves around a lot when on his back in the crib. the sleepsuit was a desperate purchase by desperate parents. short story - it works. at least for my son. it's as good as swaddling in terms of giving him the comfort he needs to sleep soundly. but we think it's better than swaddling because his arms are free. in the swaddle, my son would spend a lot of time trying to get out...we could hear and see him grunting and wriggling to try and free his arms. he'd exert a lot of energy trying to get his arms free...and often we'd find the swaddle around his neck over his face. not too safe.with the sleepsuit he sleeps with his arms spread out...and he can still put his hand to his mouth when he needs to soothe himself...and he can hold his hands together as another soothing mechanism. we are VERY surprised how well he sleeps...we decided to use the switch to the sleepsuit as a good time to also let him soothe himself to sleep...up until a couple weeks ago we'd been nursing him to sleep. that's the only way we'd get him to sleep. and if he woke in the middle of the night, we'd have to feed him again. on the FIRST night we put him in the suit and let him soothe himself to sleep, he cried for 45 minutes before finally going down. but he slept for 8 hours! previously, the longest stretch he'd done was 6. and we've gotten 8 hour stretches every night since...and we hope to get even longer ones soon (yes, we're greedy). it's only been a few days, and he still cries for a few minutes before going to sleep...we hope the crying bit ends soon, but we're thrilled that he can put himself to sleep. maybe we're more thrilled that we can get some decent sleep, too. we also put him in the suit for naps.so, this sleepsuit works for us. i totally understand that it may not be for every kid...but why not give it a go? if it doesn't work the first week, return it. a good night's sleep for you and your kid is worth the try, right?

"Must only work for some lucky babies/parents" - I wouldn't say this is a magic suit, it definitely did not meet expectations for all. Unfortunately it did not work for my little one. I was desperate to try anything, and too expensive. They should offer money back guarantee if doesn't work. Just have to add it to the list of waste of money gone down the drain :(
