Husband wants to travel overseas with baby (8 month old)

My husband wants to travel to his country overseas to visit family. I’m uncomfortable because we’ll be in rural 3rd world country, I would have to rush getting vaccinations, travel with all the baby gear and I’m exclusively pumping with rocky supply issues. I asked if we could please wait til he is a year as I would no longer need to pump and be more comfortable with health risks. He is insisting we go now. I’m just so upset he is refusing to see how traveling under these conditions is not optional at this time. Mind you his siblings travel but they are not mindful (one example didn’t use car seats at all). Also my husband doesn’t do anything with our kids to help out. Literally goes out on weekends and hangs with friends or is on his phone. Just feel so ticked that I’m the primary caregiver and when I feel uneasy it doesn’t matter!
