Ds2 will be 9 in April and has been dry since he was very young.
He's wet the bed twice this week out of nowhere and is really upset about it. 
The first time he'd had a hot chocolate in the evening which was a bit unusual, but last night he had nothing to drink before going to bed - both times it's happened first thing in the morning. It's like suddenly he can't get to the loo in time in the morning.
Any advice? Nothing stressful is going on at the moment at school or home - he's his usual happy self but obviously very upset that this has started to happen.
How many times do we wait before going to the GP - or is this a hormone/growing up thing that can happen at this age? We've got an 11 year old ds but no bed wetting experience with him at all.
Any advice gratefully received as I want to reassure him that it's ok and will stop happening!
