Review on Hiccapop 1 Pack Toddler Bumpers Toddlers by Lisa Brown

I just opened this today at around 5:08pm. Happy to use this for my son! I let it rise to the advertised 4.5" and wait about two hours (according to the instructions) before measuring again. The only thing that bothered me were the ends of the bumper - the left side seemed pretty crumpled and flat - it was the beginning of the crease when it was packed.I hope it rises appropriately.Everything seems fine on the right side.Obviously I won't put this under the mattress topper/sheet until it rises where it does should be.You can tell it fills the entire length of the crib perfectly.I was a little surprised after registering my product on the company's website,this particular product is $3 cheaper with free shipping.But you don't get a 2nd one -day prime shipping (something I've already paid for) It's still cheaper and I was a little upset about it lol - I think it should be on sale at Revain for $22 with easy shipping w earth. I'll be back in a few hours. to try it on and see how it works in general. UPDATE: So it's been 2 hours. With. I measured it and it went from 3.5 to 4 inches. We're missing 1/2 inch from what it should be. The left "crumpled and flat" side is even more animated. I measured it and it's 3.5 inches. The right side is almost the same height as when originally unpacked at 3.5 inches. I'm still not sure if I should worry or not. It didn't fully inflate where it should. and place it under the mattress topper AND the sheet. My son's mattress is organic, so it doesn't have a plastic cover but a fabric cover. I noticed that the bumper slips a bit - the mattress doesn't go past the edge to the center. My son was able to get in and out of the crib with no problems. I'm really crossing my fingers that he doesn't fall out of his crib tonight. I'll put some pillows and blankets on the floor under him (ignore the huge mess in his room - we're in the middle of a move). I just happened to read the label on this product and am very shocked to see that it is not intended for use on a cot. In fact, it is not recommended at all! Maybe I missed something or didn't read something I should have had before buying? I will still use at your own risk. I hope everything is fine.
