DS, who is 6 and in Yr1, has been been best friends with a boy Max since virtually day 1 of reception. They adore eachother and play so beautifully.
Max's family are always inviting DS on big days out; theme parks, aquarium, zoo etc. They always message me and say
'We have a family ticket for XYZ, can DS come and make use of the extra child space?'
Thing is, I can't really repay the favour. I have other children and can't fit Max in the car. I have him over to play and go local places, but can't really do full on days out. Also they go on this sort of thing a lot more than we do, it would cost a lot to try and keep up.
Is it unreasonable to keep letting DS go but then not doing the same in return?
For context, Max is an only and lives with his grandparents. His mother died when he was 2 months old and his dad sees him infrequently. There are no other family children they could take.
