SprinBuds Baby Soft Cotton Sleeping Sack Long Sleeve Wearbale Blanket Green

I LOVED these sleep sacks for my toddler!! They are so soft and cozy. The problem is the zipper split open during the night. I got my LO in the morning and the entire front was open. I thought maybe it was a fluke so I tried it for nap. Well it did the same thing, split right open. I am returning these. ):

Would love to review the actual item but since there’s no where to choose the size you need... the item I received is far too big.
