Frustrated with Motherhood

Last night I went to bed dreading the next day, and the only reason was because I would have to start all over again getting BD dressed, trying to run without interruption, feeding Pancake before her screams reached misery level. My fears were realized today when I was trying to get BD dressed for the day so we could leave the house to buy a birthday present for a three-year old's party we have tomorrow morning. You would think going to a toy store would motivate BD to cooperate, but it didn't. This is how our dialogue went (keep in mind that I was holding a crying baby while this is going on):
Me: Okay, BD it's time to get dressed.
BD: NOOOOOO. I don't want to get dressed.
Me: We can't go to the store if you're not dressed.
BD: Well, I don't want to go to the store. (I fell right into that one.)
Me: We're going to the store whether you like it or not. We need to get C a birthday present and we need to buy some wine. Now what underwear do you want to wear today?
BD: I don't want underwear. I want a diaper.
Me: Fine. (I pull out a diaper.) Come here so I can get you dressed.
BD: I don't want to get dressed. (He's wriggling all over the floor so as to evade me.)
Me: I'm not going to deal with you while you're like this. I'm going to get Pancake dressed. When you're ready to behave I'll come get you dressed.
BD follows me into Pancake's room and insists that he's ready now. We go back to his room. I try to put his diaper on.
BD: I don't want that diaper. (I grab another diaper and try again.) I don't want that diaper either.
Me to myself: Jesus Christ BD make up your f***ing mind!
Me out loud: These are the only two choices so you better choose one or I'm going to choose for you.
BD: Well, I don't want any diaper. I don't want any pants either. (Finally he points to one. I put it on him and start putting pants on -- pants that he did not pick out.)
BD: I don't want those pants! I don't want this diaper! I want underwear!
Me: You told me you wanted a diaper.
BD: I want these underwear. (He pulls out airplane underwear from the drawer.)
I yank the pants off, then the diaper. I put the underwear on and ask him what pants he wants with a selection of four pairs on the floor. BD refuses to choose pants. And the saga continues.
We finally left the house about 45 minutes later.

Our outing was uneventful and Pancake even slept so I could get all of my errands run. I never used the drive-through at the bank before I had kids. Now I realize what a convenience it is, when they don't make you wait that is. BD picked out his next toy for the imminent completion of his latest potty chart. This one requires 49 stickers for a present and BD has 43 -- not one is for pooping. "I don't like to poop on the potty. I only like to pee." Great!
