It seems that in every family there has been a great-aunty or a friend of an elder relative who had a 'hare lip' when they were younger.  You will notice the reference to the older generation and that is with reason. 

The term Hare Lip belongs in the dark ages!!  Please do not use it anymore.  

Back when people believed superstitious malarkey in relation to the cause of a Cleft Lip they would claim wildly that the mother had been scared by a Hare during the pregnancy and that is why the baby was born with a cleft. Oddly, it is more like that after the repair was carried out the scar formed in the same shape as the face of a Hare.  If you're scratching your head right now and asking how that could be believed, you are not alone!  Why wasn't it called a Cat Lip? They look similar!  But I digress...

Today it is heard with certain 'cringe factor' for those of us with a loved one who is cleft-affected. 

Basically, it's insulting in today's 'enlightened' age.   Even without intention, calling someone a name that implies that they look like a rabbit or 'hare' is nothing other than insulting. 

CleftPALS hopes the name dies out soon along with all the people who had a great-aunty or a friend of an elder relative who had a 'hare lip' when they were younger. 

Please encourage the use of the correct terms Cleft Lip - or Repaired Cleft Lip, if you have to be precise.
