Hello. We are new to RVing and I am 3 months pregnant. We are looking for an RV that is suitable for a newborn baby. I would appreciate some advice about what we need to do and what size RV or motorhome we should be looking for. Can we do this in a smaller one or do we need to get a really big one? What is the minimum size? We will be living and traveling with the baby in the RV full time. Thanks!!
