In-home daycares

DS
I've been researching day care options and the most affordable option seems to be in home day care. I was hesitant to begin with about daycare just because I'm paranoid about people going crazy, so I've got my gaurd up on home daycares too. I know it can happen anywhere, but this mama bear is already protective lol. Just curious to hear experiences you've had with using an in home day care. What types of questions did you ask during interview? Im a first time mom so I just wanna make sure I cover all my bases!
