Mystified by a 3 year old

This last weekend mostly sucked. There were a few bright moments:
- swimming with the kids
- having my BFF from college over for dinner
- getting to eat the rest of the cake while the kids were napping

Otherwise, it was lame. Jeff was cranky all weekend long. He was even cranky during family night when we watched Toy Story 2. How can you be cranky during TS2? Bob is going through some kind of strange toddler phase. He turns into a mess for no apparent reason and then won't snap out of it. I'm going to have to hone my patience because so far, I haven't been doing well with the emotional breakdowns several times a day. After swimming, I turned into the mommy I never wanted to be. Bob had an accident in the bathroom while we were trying to get to the potty. So, I was cleaning it up and then putting a fresh pair of pants on him and I told him to pull them up and he started screaming and was just standing in the bathroom stall with his pants around his legs crying. I think he was experiencing low blood sugar because I know I just wanted to go home and get lunch. But I was so frustrated and we ended up sitting on the floor of the dressing room while he cried and I kept saying "I don't know what the problem is. Can you tell me what is wrong?" as tens of people walked by staring at me. Luckily, Kiera seemed happy to stand next to us and people watch. But sometimes, I wonder if she is learning the wrong message from all these interactions. She keeps saying things like, "I don't cry, Mommy" and I keep telling her it is ok to cry. Sigh.
