It will be a big challenge. Maine has a dearth of providers for kids with intellectual disability, especially in rural areas. Some of her medical conditions, which I assume require specialist care, are almost certainly going to require trips to Portland or Boston for management. I would also worry about access to emergency care that is equipped to deal with a kid with these needs. Aside from all that, it may be hard to access services in the school system. I would think really hard about this move.
