Shared Finances during pregnancy

Curious for other families. If you and your husb have almost similar income, do you go 50-50 on all the hosp and medical bills or do the husb contribute more since we are the 1 carrying a the baby. Right now I am also going on hospital visits alone and husb only goes on "important" scans. As I am the 1 doing hospital trips by myself, which is tiring just driving to and fro and as I am high risk, I need to go down more frequently. And I am also the 1 going thru all preggy changes and symptoms. I am not complaining but curious to how other couples manage and share their baby finances and see which are good and useful to adopt. #family #finances
