Yes, but we hear that it's all but impossible to travel internationally. From what we're told, you can try, but in the end your efforts will be futile.
Yes, but you'll have to pay for all travel-related expenses yourself.
Yes, but you may not want to, depending on the needs of your children.
When our kids moved in we already had an upcoming vacation planned. So two weeks after they joined our family, we traveled with them for the first time. In hindsight, we probably shouldn't have done this. The kids were still settling in and becoming accustomed to our family's rules and routines - things that generally become pretty relaxed while on vacation. They were also still learning to accept us as the parental authority figures, which was confused by having other adult family members in such close quarters. While we did all survive the trip, and we even have a lot of fun memories from it, we decided afterwards not to travel again for quite some time.We waited another five months - until Thanksgiving - to attempt traveling again. This time it was a completely different experience, for the better! The kids fit seamlessly into our family by this point. They felt secure enough to trust that this would be a good experience without having endless anxiety about the new experiences. We, as parents, felt much more confident to express our family's needs and expectations to the extended family members we were traveling with.
Our children have relatively few special needs. Families parenting children with more extreme challenges may find that they need to wait longer to travel, or may decide to forgo traveling all together. Foster parenting forces you to re-examine your priorities, and find creative ways to enjoy your family time together. Sometimes that means changing your usual travel plans in order to best accommodate the needs of your children.
