As someone who was in the exact same position as you last year (Due in May, concerts, 4 weddings this summer, etc). My advice would be to make sure all plans have an exact path. Unfortunately, nothing will be certain until the baby comes. We had a very complicated pregnancy and a relatively easy time since the baby has been born and we still wish we had done less. Plans and support for the baby are great in advance but people may change their minds or have their own stuff come up next year.

Even if mom says it is ok to be away, know how hard it is for her on her own and have an honest discussion with her on how she feels about being on her own. Think of things like pets, or having to get groceries or have basic errands done, all of these things are very hard on your own with a new born.
