How much would you pay for photography services?

As

I'm starting a photography business but I'm not sure how much is fair to charge. I have been doing it for years but not charging enough to be able to work from home doing it. It was more of a hobby while I worked full-time.

What is a reasonable price for things like family photography, newborn photography, senior photos, etc? I tried looking at competitors but their prices are all over the place.
