Need Advice About Vans

My husband and I will be getting a van by fall... I'm a nervous wreck... Never drove a bigger vehicles than a sedan.

I'm 4'10" and petite.... I just want enough time to get used to before winter... I almost want to put it off till next spring too but one though we are in need of bigger vehicle before our #3 arrives. Currently, we both drove sedan.

How did you adjust? Was it pretty easy? What do you like and don't like about the van you have currently?
