Bumper pad madness!!

We all know that bumper pads in the crib are dang cute and they seem like a must! However, Avery has become quite the crazy sleeper. She's everywhere!! Erik and I are so nervous she is going to suffocate in those dang bumpers because she gets her face right in them. I check on her at least once a night. Last night I got up at three am, went and checked on her and she was kind of stirring a little. I found her grabbing onto to the bumper, pulling it down over her face, trying to get it in her mouth and all the while, she's still asleep!! I moved her back to the middle of the crib and went back to bed. I couldn't sleep so I checked on her again. Low and behold she was at it again, trying to get the bumper pad into her mouth. We normally don't feed her at night, but something told me she might be hungry. So here I am at three thirty feeding her. I put her back to sleep and she does it again. I was so bugged, Erik and I ripped them out. She was mad and threw a fit. We thought we would let her cry it out for a bit. We must have been so tired cause neither of us know when or if she stopped crying. Erik woke to her screaming at five thirty. He went and got her, came barging through our bedroom door, screaming, "She is having an allergic reaction!" I jumped out of bed to find her eyes and lips completely swollen. Erik ran to the nearest pharmacy for benadryl. Crying usually doesn't make her lips swell so I checked her body for any bug bites and nothing. By the time Erik got home, the swelling had already gone down quite a bit. We are so confused as to what happened. We're thinking maybe she was sucking on the crib and the paint caused a reaction. Who the heck knows. I guess I'll never take those dang bumper pads out again.
