My DD used to always take her nappy off, not to run around naked it was just because she could do it. I resorted to using nappy pants on her as these were harder to get off and she stopped trying to get them off. Now however she has gone back to normal nappies again and is fine (after about 3mths of nappy pants use) but she does insist on taking her nappy off for bath time or when she gets dressed or needs a nappy changed.

Unfortunately sher decided after she had a dirty nappy one day to take off all her clothes including the nappy and then come tell us she had a pooey bum. Luckily the nappy stayed upright and she didn't sit down anywhere.
