Since having my first child the relationship with my MIL has become quite tense. I am pregnant again and she wants us to visit them for Christmas, I'll be 35 weeks pregnant and they live 7-8 hours drive from us. I find it uncomfortable to be in a car at the best of times , let alone for that long and that pregnant. I understand that they want to see their grandchild and they visit to see him every 3-4 months (dont help with him or play with him unless encouraged), my MIL wants then my husband and my son to visit her without me and I am not keen on that. Am I being unreasonable?
