I am still in first trimester and plan to use an in home daycare of somesort (probably)...when should I start looking/inquiring with people. I have a recommendation from a friend, but don't want her to think I'm crazy for calling so early

I also hate for someone to be faster than me and snap up a precious infant spot.
Re: when to start looking for daycare
I would love to put baby in a home day care vs. a large center, but have no clue where to even start looking.
Can anyone recommend any websites to start from?
