How did your life change after being a father?

When our first daughter was born, I had a lot of mixed feeling; I was crying , I was rejoicing, I was asking myself how am I going to give the best for this tiny human. Starting from that moment, one fear is constant if something will happen to my daughter.
As she is growing, I often feel if we ade missing something that she should get. Like does she have enough toys, introducing her to activities as she grows etc.
Being father is a pleasure but it is also constant fear for the child and own life situation.
After being father I became more conscious about my own health, what if something happens to me?
