The sleep sack was beautifully packaged and felt exquisitely made. I got the 6-12 months for my 7 month old, 17lb baby and it swallowed him. I had to roll the sleeves three times and often his arms would get lost inside the sleeper. (Which is HORRIBLE for a finger sucker!! Oh the drama!!) We keep our bedroom around 62 degrees so I put a onesie on him under the sleep sack. I checked him in the middle of the night and his body was freezing..especially his feet. Surprisingly his face and hands never get cold!!! He absolutely HATES being hot so there’s that. Anyway, I suppose it’ll be good if I put a sleeper on underneath like we did with his 1.0 TOG Woombie. The Spud is literally so dreamy. So soft, cushiony, extremely well-made and the bottom buttons are a middle of the night diaper change gamechanger. Unfortunately after only using it for less than a week, I found a kink in the zipper teeth near his neck. It was during the night because when i turned him over to change him, the whole zipper was open. I have no idea how it happened. So the zipper couldn’t be opened..and fortunately I could get it over his head so I wouldn’t have to destroy it to get it off. Though I really loved it, I think I’ll lean into something warmer like wool. But definitely check this one out!
Love this sleep sack, baby went from merlin sleep suit to this and sleeps well BUT the zipper is such a pain. It broke within a few days and constantly sticks/comes off
This is our 2nd one and the zipper broke again. I wonât be buying this brand anymore.
This is a high quality, well-made item that will help baby to transition out of swaddling. These wearable blankets give the hips the room they need but cannot be kicked off leaving baby cold. This item has detachable sleeves (they have literally thought of everything) and has safe, covered zips and smooth snaps all along the bottom making it easy to change your baby. The material that tops this quilted item and the material that faces your baby is like a teeshirt material so very comfortable. It is recommended to put it in a wash bag and wash on gentle. The whole item is 100% cotton so very absorbent. This does not come with a specific guide for temperatures but it does state that it is for use in “chilly” weather/rooms.
The little spud thermostat sleep sack is wonderful when your child is traveling and you need to put them in the car seat because itâs not too bulky. It gives him plenty of room to wiggle around if necessary. Is made of beautiful material that can be washed easily. Itâs open at the bottom as well as zippers so that they can get in and out easily, the sleeves detached so if you want to cool them a little bit, you just take the sleeves off! This is a truly clever bunting for your child
