Title says it all really, DD who has just turned 3 has been potty trained for a few months now but has also had dry nappies at night for the past few mornings. DS who is 4 is still waking up with full nappies in the morning. How do I go about this situation as I don’t want DS to start refusing refusing to wear his night nappy or get upset that his younger sister is dry before him. Anyone been in a similar situation?
