Honestly in your situation I would possibly consider going back to work after this mat leave ends in order to get the hours for your next mat leave. Then after that start your dayhome. Or you can start your dayhome and just take a shorter maternity leave perhaps a month.

But mostly congratulations! I myself just found out I'm expecting so I totally get the stress of planning for a maternity leave. I have only been open since May so I'm still getting established. Don't worry you'll figure it out... don't stress too much, not goot for the babe.
