I agree with Playfelt. I am almost in the same situation than you. I have always had 4 kids max for close to 6 years that I open been in this business. I have a mom that has been with me since the beginning (now with the second child). We became friends when the older graduated and was not my client anymore. We keep friends now. I told her my plans to have 5 kids after my son become 2 years old when she enrolled the 2nd girl. She forgot and now that I told her someone will join us in June and will have 5 kids, She looked surprise and uncomfortable and asked if that were the plans (she forgets things so I believe she really forgot about it). She now made peace with it. She is my friend but this is my business and my source of income. She has respected that so far that is why we continue being friends with her and have good relationship as a client. She now understands my position since I explain again the reasons I told her at the beginning.
