Believe me her nappy punishment works! Due to a major mix-up with the shippers our seat did not get back to us for so long that the company said that they did not want the loaner back as it was too old so we should keep both - I guess they got compensation from the shippers for loosing our seat for 4 months.
On the day of the wedding,me and my two sisters and a cousin took her to the church nursery and told her we were going to dress her there rather than in the bridal dressing room.
As soon as she was done, Cora got off the changing table and walked over to the closet to get her younger sister a pair of plastic pants that she forced her to wear.
She came stomping back down stairs asking what nappies were doing in her room, quite calmly I told her they were her's and to go back up to her room and undress as I would be up to put them on her.
Now you can wear the outfit, after all, it does hide your diaper.
My daughter is quite petite so the diaper would fit her as well as it would fit a baby.
