DD has a loose ish group of six school friends and one of the mums usually coordinates holiday clubs so three or four of them would do the same club for a week or two. DD loves that as her brother usually goes to a football club and she isn't keen. However, each day, the same mum usually picks up the other girls whoever happens to be around that week for a group playdate/childcare. Obviously that's all fine. However, DD is regularly upset as she feels excluded. I have tried to invite the friend to ours but the usual response is 'oh we are having so and so over.....' During term time DD also does a couple of activities with this friend when we usually take turns taking the girls there and back.
Obviously no one owes anyone playdates. But DD is also the only one who is always excluded and she counts this girl as one of her best friends. How would you best manage it?
