Bubs felt super uncomfortable and restricted in this, he didn't even stay down for a nap. It also made late night feeding awkward with the arms bent that way. I don't think it works for every baby especially if they are more active and want to change their arm positioning during sleep.

While the arms up design is good, I would not have expected that after one week the swaddle would have pilling from a wriggly baby. I have some cheaper zip swaddles which have been used for well over a month which are in better condition. Disappointed given the price of these swaddles.

I have two of these swaddles. The first is an older design (did not realise as I bought it second hand) and it really does not provide enough room for good hip development. The second was a new one and it looks like they changed the design to enable more hip room, but then we found the chest size to be so tight that the swaddle would twist around him during the night and it all bunched up under his neck. Our Bub was at the bottom end of the small size so I hate to imagine how awful this would be on him as he got a little bigger. Not good designs in my opinion. They are also made of quite thin stretchy cotton and are very expensive for what they are. I would not buy these again.

Pretty much the first time we used it we needed to use napisan on it. It left big white patches. We only put it on for 15 minutes before putting in the washing machine. A product for babies should really be colorfast. Otherwise it helps him sleep. But watchout, our newborn can move around quite a lot by kicking with this product on.

Great for newborns up to 4 months old. After that my son got way too dependent on having his arms wrapped to sleep. Also I found that even when not sleeping, his arms are constantly in the upright position. I wonder if any studies have been taken on long term effects !
I think if weaned out of the suit early enough, this issue would be avoided.
My baby sleeps so well in it
Prolonged use has bad effects
