How does married life change after having a baby? Would like to be mentally prepared for this and not taken by surprise!

My daughter is turning 8months soon and I don't think my married life have changed much in terms of relationship but more of activities we can do after having her. We used to catch all the latest movies in the Cinema with no planning ahead required but now we have to plan ahead with our baby sitter and only do mid night movies. Other than that, my husband is a very hands on dad and so far the relationship is as good as before.
