Haha, yes, they LOVE to say no! And just because they can! Even when you are telling them, and not asking, because after a series of no no no, you are fed-up and are down right TELLING them, LOL... But, I always try to find one thing to say I'm not going to do for my DD if she doesn't comply. Example; if it's bed time and she gives me the No's to brushing, then I say "well, then I won't read books" (it's her favorite part of bedtime, you'll have to use your DD's fav thing) but that works, and she comes running. Ex; If we planned a trip to the mall/grocery etc.. and she doesn't want to get ready, then I say, "well then I'm leaving, I have to go, you can stay" (and I grab my keys) she comes running. Or, I will say "then we won't stop at the Teddy Bear store" (at the mall, we always have to stop for 5 minutes for her to look, another fav thing). I also tell her, that if she says No to me, then I will start saying No to her, and then I do for EVERYTHING as teaser, she gets it, starts laughing, and then complies as she is saying "Nooooo"... The thing I have found, is to not let it frustrate you, but, be thinking ahead for the antidote! It's definitely a phase that will keep you on your toes! Good luck!!
