Baby BrezzaBaby Brezza 2-in-1 Double Zipper Baby Sleepsuit - Unique Swaddle Transition Sleepsuit - Breathable with Mesh Panels - Converts from Sleepsuit to Sleep Vest, 3-6 Months, Cream

I have a 4 month old who has just learned to roll over but still has a startle reflex so I couldn’t swaddle him anymore, but also couldn’t just put him in a sleep sack as he’d wake himself up immediately. I bought this one and the Merlin Sleep Suit as both had amazing reviews. It’s hot where I live and my baby is also a very hot sleeper. I noticed this one has side vents and the arms detach so I thought I’d give it a try in hopes it’ll help keep my baby cool. He slept AMAZING! I didn’t even bother opening the marlin one and am actually returning to buy a backup of this one. It keeps My baby cool and helps him sleep great (granted, you have to take the proper steps to ensure your baby is sleepy so they will actually sleep 8+ hours straight). But this sleep suit really does help. As a first time mom who was willing to try anything to help myself (and baby) get a good (or better) nights rest, I fully 100% believe this is worth the money. Save yourself the $10 or whatever amount and buy this over the marlin ones. Or at least try this one first. It worked for my baby and may even work for yoursI just wish the next size (6-9 month) was available. This one does shrink a little after the wash. Even washing on cold and drying on cool temp. I’ll keep an eye out for the next size in hopes it becomes available.

The Merlin suit worked really well for my first baby, but I was nervous about using it for my second since they were born during this hot summer. This has mesh around the legs and all up and down the sides. I still put my baby in this with only a diaper since it's summer, but I feel a lot better knowing that there's some airflow. They don't seem hot when I check on them and they sleep so peacefully. They're logging longer naps now and seem to like it better than restrictive swaddles.

I tried every swaddle, and sleep suit available, also have the Merlin sleep suit for comparison, what I love about this suit is that it has the option to remove the sleeves, allowing baby to move arms. Material is great! Also Chas to mesh panels so baby doesn’t get hot, like he gets with a swaddle . I really like it and about to order a second one to alternate

If your baby has a strong moro reflex. This may not work for you.

Loved everything about this- easy to use, breathable, helped baby sleep. Only wish they made a next size up!

Got this and the Merlin to see which features we and baby liked best. This is lighter than the Merlin and has more features (removable arms and breathable mesh), but baby just sleeps better in the Merlin for some reason - maybe the extra thickness? We sent the Brezza back.

Very good. Works like the Merlin, but gives my baby some air, as he runs hot.

Great "blanket" and transition from swaddling to sleeping in a "bag blanket". It seems my grandson had no issues sleeping stretches at nite with this. Without this at naptime, he often seemed to awaken earlier than necessary because his movements awakened him. This provides a tiny bit of restriction to allow continued sleep.
