Focus on business or focus on family

I have recently had an unexpected uptick in new clients, at the same time, my wife and I have decided the time is right to have our another child.

When I started the business, my youngest was just a baby and I worked at home, which was great. As he and the business grew, I moved my office and he went to childcare during the day.

Now, with the new work coming and a new baby not far behind, I'm questioning whether or not something will have to give. I enjoy my current clients but am wondering how to handle the addition work along with family obligations.

Are any of you parents who have faced a similar situation? Would you recommend not taking on the new clients and focus on family first?
