Don't worry my daughter did the exact same thing. I was doing loundry and cleaning her crib constantly. I went and bought those big baby pins with plastic on them and I would put her in a zip up onsie when I put her to bed or a nap. At the top where the zipper goes up I pinned it. It works awesome. She couldn't get the pins undone to take her diaper off. This summer you could get those thin zip up onsies. Eventually after a few months you can stop using them and she won't even try to take her onsie off. I called the pins oweees so she knew they would stick her when I was changeing her clothes and diaper. Trust me it works. L. in Clinton .
