I think it's great that your husband wants to partner with you in your business. When working in a center, we LOVED having male teachers as we had a lot of kids that did not have dads at home, so they always loved the running around crazy play that the male teachers would do that the female teachers were less likely to do (not trying to generalize, just saying what we experienced).

I think it would be a shame if families didn't want to go with a provider because one of the providers was male, but I think that some families may choose to not sign up with you. Hopefully you have some long term families that would definitely stay and they can then be references for you and your husband when you get more families.
