Reply to 18 month old hates potty

My daughter went through the same phase around the same time. (She’s now 21 months.) I gave it a rest for a couple weeks, then just started being really matter of fact about it: She signs “potty”, I acknowledge it and say, “Ok! Pick out a book, and we’ll go to the potty.” And we go from there. I also stopped making a big deal RIGHT when she’s doing it. We celebrate a little after the fact, like when we’ve finished the book and are cleaning up/flushing. I think there was a little embarrassment happening when I made a big deal during the act, but that’s just my theory.
