Thanks everyone! Just to clarify, I am due in October - I'm only 9 weeks now but will be closing in June. I have a herniated disc in my back which caused me a lot of pain in my third trimester with my last pregnancy so am preparing for that to happen again. I also just want the time alone with my two kids and to enjoy a less stressful summer.
I am starting to develop a little belly but am going to pass it off as weight gain for as long as a can! I know that at least one family will leave ASAP once I tell them I am expecting so I'm pretty nervous about that.
Someone suggested that I tell them I'm pregnant when I can no longer hide it, tell them I will be open until my due date and then 'unexpectedly' close in June but I don't feel comfortable doing that especially since it is more difficult to find daycare in the summer.
