I have had loads of my DS's friends back to mine for play dates but I hardly ever get invitations back? why? I understand that some mums work late, use childcare, but surely they could spare a couple of hours at the weekend to reciprocate the arrangement? I feel it's common courtesy really. I'm just sick of it being so one sided. My son would love to be invited to his friends' houses. There is just one friend's family here that seems to appreciate that it should be a reciprocal arrangement.
