Lesvos is quiet and probably not too much to do for children I think you would be far better going to Parga with him loads going on there. We go to Lesvos every year and stay in Molyvos and never see many children. We were in Parga as well this year and have booked again for next July.

We stayed in Petra when we went to Lesvos. It's quite a way from the airport but it is worth it.
The beach was lovely and the locals very friendly. We didn't see to many kids but to be honest it wasn't school holiday time.
It was one of these places where you could go into the kitchen to pick what you wanted to eat. The nightlife wasn't 'jumping' - it was mainly around a few tavernas and bars however I understand that there has been some building there since we were there so it's worth checking it out.

I stayed in Petra about 8 years ago and really liked it. It has a rugged beauty and you can walk to Molyvos from there (or of course get a taxi).

I totally recommend!

Have had many very happy holidays in Lesvos.

We took our kids when they were little and again when they were more Kevin & Perry age and they loved it but in all honesty they had to make their own fun.

We love Petra and Molyvos although not so keen on Anaxos which doesnt do it for us. If you do go, book a taxi from the airport or hire a car as the coach transfers can be a mare, taking perhaps an hour and a half to 2 hours to Petra/Molyvos.

We went to Lesvos (Petra) this September. Found it to be less 'touristy' than other Greek islands, but this is what we liked about it, so we had a wonderful time. As others have said, there were not that many children around though.
There are the odd music bars dotted around, but when we were there, they were not open. Maybe in high season?
We stayed at the Panorama hotel in Petra on a B&B basis. I can recommend this hotel. I have done a review on that and the resort on here if you require more information.
