Arguing with a two year old...who wins?

Yesterday, I found myself caught right in the middle of an argument with Grey (again)...I use the word argument lightly. I realize of course, that I am the adult and could stop this immediately, but its usually too late and I am caught. At breakfast, I asked Grey if he wanted a spoon or a fork. Without allowing him to respond I said, "Nevermind...a fork would be best." Grey immediately responded by saying, "Mo, a moon." I explained that a fork would be best to use because he was eating eggs. His response was the same. I then sat down and explained (again) why a fork would be best showing him the difference between a fork and a spoon. Didn't help - same response. I then realized there's no hope in winning this so I gave him the "moon". Of course you do realize that if I would have told him the spoon would have been best, he would have wanted the fork.

I think Grey likes to have certain arguments with me because he knows I will fall for it. His favorite is during a diaper change. It is his responsibility to get out his diaper and wipes for me and bring them to where I am. He has two different diapers - daytime and nighttime - And, Grey knows the difference between the two - "daytime bo" and "night-night bo".

Usually our conversation will go like this most daily:

Me: Do you need a diaper change?

Grey: Mo (this is his immediate response for most everything)

Me: Grey...let me see. Yes, you need a new diaper - go get the diaper and wipes.

Grey: (in a sweet innocent voice) night-night bo?

Me: No, Grey. It's daytime. You need your daytime diaper.

Grey: Night-night bo?

Me: No. Go get the right diaper.

Grey: Running and crying to his room "NIGHT-NIGHT BO!"

Me: Grey, we go through this all the time. You know the right diaper to get out.

Finally, Grey will get out the correct diaper and bring it to me or by this time, I have followed him into his room. As I am changing his diaper, he will say. "Daytime Bo" and smile.

Now, of course, I should catch on and sometimes I do, but I really think he enjoys this "argument".

And, I ask again...who wins? : )
