Traveling with toddler

We have a 2 year old and are expecting. We travel every few weeks/months, never know how long we will be there or where we are going next. Not traveling is Not an option. However, does anyone have any ideas on how we can keep our daughter and when the new baby comes up to date with doctor visits? We try to schedule around it but we just never know where we will be going or how long we will be there so it’s hard. We usually get 1-5 days notice before we move again. 99% of doctors won’t take her in time or won’t take her at all Because they have to transfer records and that takes a while.
