DS (5 in August, dry at night for a year or so) out of blue 6 weeks or so ago started wetting the bed 2-3 times/week. Can't see any link between fluid intake in the day. Nothing (obviously) stressful going on for him at the moment (no new siblings, schooling etc etc). I am wondering whether to put him back in nappies at night - am not keen to do this (2 yo DD is nappy free and he won't want to be 'behind' her).
Any ideas a) why this might be happening; b) what to do to help DS get back to being reliably dry and c) how to best deal with it? We are currently still using cot beds and were hoping to move both children to single bunk later the year so don't want to be buying new waterproof bedding which will be too small within a matter of months.
Grateful for advice. Thanks.
