Pushing buttons

I believe we have hit the "terrible twos". Over the past few days Claire has been pushing my buttons to no end. She has started to tell me that she doesn't want something, and when given a choice to make, she won't say anything. I give her warning and inform her of what will happen and she still remains quiet. So, when the time is up, I follow through with what I tell her will happen if she doesn't answer. At that point she goes into extreme meltdown mode which takes many minutes and lots of patience on my part to get through!
Claire also started asking "why" for everything. This seems to have happened overnight. Today was the first day she has hit me hard with "why" for every single thing I say. Patience is key and this too shall pass!
On the bright side, we just finished day 4 of wearing "big girl panties" and have had no accidents in these 4 days! Claire even sleeps in her panties and thankfully, no wet bed so far. I am very proud of how quickly she caught on this time with the potty training. I guess if I would have just waited for her to be ready, I could have bypassed the torture we went through when Mommy thought it was time to get potty trained!
