I would tell your DH to go for it i run my own family day care and my DH is a co carer with me and the children love doing activities with him and they really learn from having that male role model its great for the children, I think people need to encourge males more in this industry, When doing a childcare course before coming a carer there were many males in my class, and there experences and knowledge was just as good and sometimes better then the females in my class. so i say if thats what your husband wants to do go for it, and working with children is the best job in the world...
