So we are a blended family, I have one son, my partner has two. My son is with us full time, them two come for half week. My partner is fairly active when his kids come. He is much more lively around his kids, plays games with them , takes them swimming etc. When they leave, he kind of switches off the parenting role and is more to himself. He speaks to my son, standard short conversations - How was your day at school etc, but does not really interact with him. My son can obviously feel that and I think it's making him feel like he is not good enough or not worth the attention when they are gone. I care about all 3 boys just the same, I cook, wash and run around the house and pop the head into their room to have a quick chat, I don't really do activities with any of them so I am worried he will throw it into my face if I complain. How much time does your partner spend with your kids? Any insights and experience welcome:)
