Oooooh, nothing like some thinly veiled criticism to make you feel like crap, huh??
First; I don't think I would bother responding. Unless it was to say "Thank you for your time, good luck in your search." (And that would just be for the good karma, lol)
Second; thank your stars that you don't have to deal with this future nightmare of a parent!!! She has trouble written all over, if indeed she is a parent looking for childcare (I also think she may just be snooping, for someone). Hope this gal figures out that regulations in the two provinces she is comparing are COMPLETELY different.
Third; she is, as playfelt mentioned, quickly going to learn that she needs to adjust her standards in what she is looking for in a home daycare. I realize that there are many home providers with the "credentials" she is seeking. I would hazard a guess though, that there are MANY, many more without. And, as I have said a time or two before; that doesn't make them better or worse!! Just different.
And if her sister is so super-awesome, why doesn't she move to BC and get her to watch her kids....
