Ms C was potty trained when she was about 2 years and 9 months old.  We hate the mess and had bought her a waterproof bed sheet in additional to her wearing her night time nappy.  She has been dry at night since she was potty trained but my husband and I chose to keep her wearing the night time nappy until now.  Out of the blue, she told me that she is a big girl and she doesn’t want to wear a nappy.  I was really proud of her. Today is her 3rd day wearing “big girl pants” at night – so far so good!
