This is ridiculous that she is almost 4 and she is terrified. She did it at the dentist fine, but at home she sobs and cries. The toothpaste is safe enough that she doesn't spit it out, but I am at wit's end.
If either of us even mention that she needs to rinse, her eyes well up and she is obviously panicking and freaked out. My husband tries to get her happy by joking around and letting water dribble out of his mouth onto his shirt, and she laughs, but she won't try. I've also had my aunt try to get her to do it, but DD just starts crying and you can be in the bathroom for an hour trying to convince her, but she is basically a sobbing mess.
So ridiculous.. I can only hope it passes like the phase where she was terrified of bubbles in the bath! BTW she is generally very outgoing, not shy or scared of stuff, she goes on scary rides at the amusement park and is one of the bolder kids in her class, so I have no idea how to handle this.
