Review on 🛀 2-Pack Waterproof Bassinet Sheets - No Need for Mattress Pad Cover - Taupe Splash & Stripes - Unisex Baby Bedding for Boys & Girls by Francesca Engel

I ordered this for the mattress topper that comes with the Grayco Pack n Play. Although they technically fit, I can go around all corners, they are too tight. Because the panel has folds for folding, the sheets compress the mattress panel and form lumps of foam. It's too tight. I'm tempted to cut the rubber band to see if that helps. I'm a bit squeamish that a sagging mattress poses a risk for SIDS, but I rest my baby's head on the end that doesn't wrinkle. I'm not sure if it becomes a bigger problem as the size increases. I haven't had a chance to test the waterproofness yet as there have been no accidents with the baby. EDIT: They seem to stretch after this far and fit a little better. However, it took me a few months.
