Hi Lisa! There is another thread on here somewhere where I got lots of great advice! I am 7 months along now so can tell you what I have done. I told my families at 3 months. I sent everyone an email on a Saturday.....partly so they could discuss it before talking to me about it and partly because I'm a big old chicken, haha!! All of my families were great, sad that I was closing but really excited for us! I was prepared to lose everyone straight away but they are all staying to the bitter end! I think the most important thing is to have a very organized plan in place before you tell parents. Outline everything from how long you will have off, emergency plans if things don't go as planned, changes you might have to make in the later months etc. Don't forget to have a plan for all those dr. appointments...will parents have to take their kids home or can someone cover for you? Hopefully when parents see that you have thought everything through and have a solid plan they will be happy for you!
