if you need time off to care for your husband that you should do it. I personally would not count this as my vacation time. This is for family/medical reasons. I value my vacation time and this is something that you need to do for your family. Sadly whenever we take extra time off, we run the risk of parents bolting but family comes first and dont feel bad about that. I have never quoted exactly how much time I will take off, I give a range so that I have options. In this business we need more that 2 weeks off in a year. explain the situation to the families, and do what you need to do. In the past I have suggested to my clients that they help each other out by watching each others kids and therefore having to each take less time off. I hope surgery and recovery go well for your hubby.
