Since so many people have asked, I thought I would share it with everyone. A gal who adopted from the same creche as our boys were in, just moved to Haiti to be the houseparents for 20 or so children in the Haitian Children's Home. I asked her via Facebook how to say " please don't whine" and she responded. I must tell everyone she is my new best friend and she saved me from wearing ear-plugs most of the day.
So here it is......pa plenyen sooplay. Phoenetically it is, pa play eh, sooplay. I have this odd feeling that this phrase will be uttered in many homes with Haitian children. It ranks right up there with 'pa touche' and Sispan sa, in our house right now.
Hope this helps!
