I empathize ... personally if the pregnant parent was not using the offer of an out as a hope that you would TAKE IT cause she wants out of her commitment too and feels trapped because of the friendship of your other client than I would keep my commitment if she needs and wants the care for 5 months - keep the referrals contact info and put them on a 'wait list' for the next space cause you never know what might happen between now and few weeks someone else might get laid off and so forth - things often have a way of working out.

You have 5 months notice to advertize and find a replacement for the client you've committed to - so much can happen in 5 months time for sure!

Personally while I get the desire to ditch a client you know is leaving anyway (struggling with that temptation myself but holding strong to seeing it through til August) ... IMO we have to keep karma in mind when we are making our business decisions - it is not necessarily BEST to terminate a client who has not shown JUST CAUSE (aka breach of contract) just for a better financial option because it can have negative impacts that affect FUTURE options for us .... if you are getting a lot of word of mouth referrals it is likely because people find you fair and professional and TRUST you - you want to PROTECT that by behaving in a manner that is conducive to that ..... IMO terminating a now pregnant mama because she is only going to need 5 months of care in favor of what seems like a 'better financial deal' might turn out to bite you in the ass if word of mouth travels that this is your practice

I understand that it sucks for us when clients we had thought would be 'long term' turn out to be short term I really do .... however it is a risk we assume when being self employed basically the biggest commitment we have from clients is the 'notice periods' we negotiate into our contracts - I also get that it feels we have been 'lied to' when someone signs on and does not disclose their family status - but the fact remains that pregnant women are under no obligation to 'inform' us of their pregnancy when they enter into a contract and 'discriminating' against a women and refusing her service based on her pregnancy is against the Human Rights Code ... doing so could find your business sued which is a huge financial risk for sure!
