Just Teething You
Rivka was holding her little baby Yitzy, while talking to her mother. "I haven't slept in three days," Rivka complained. "Yitzy is teething and he's up all night crying."
"Why don't you just rub a thimble-full of brandy on his gums. That will numb them up and put him right to sleep." answered the new Bubbie.
"I can't give my baby alcohol! Who knows what that will do to him."
“Yitzy will be fine, I guarantee it!” said the Bubbie.
“How can you guarantee something like that?” asked Rivka.
"Because I did it to you every night and you turned out OK!"
