3rd Trimester?

So according to some sources I started the 3rd trimester yesterday, but other sources say it doesn't start until 28 weeks, which is next Sunday. Either way I'm nearing the finish line.

Peanut is moving around quite a bit and I have noticed she has fallen into a schedule. She is usually awake and moving by 6am and stays that way till about 7:30am. She then moves a lot after I eat lunch, usually for about 30 minutes. And then again at night around 9:30-10pm she starts moving, this time for about 2-3 hours. I can get her to move other times of the day by sitting in certain positions, being around louder noises, and eating/drinking cold things. This schedule actually isn't that bad and I wouldn't mind if she continued something similar to it once she is born, but I'm not holding my breath.

I was at work the other evening and Peanut was being super active because I just had some ice water. One of the social workers at my job came in to pick up something he forgot and brought his daughter with him. I think she is around 6 years old. Her dad was talking to her about how I am going to have a baby girl and that she was in her mom's tummy just like my little girl is in mine. She just kept staring at my stomach with this weird expression until her dad asked her what was wrong. She said "It keeps moving", with really big eyes. I hadn't thought about the fact that I was wearing a tighter shirt that day and most of Peanut's movements are now big enough to be seen from the outside. I think it scared the little girl though. I asked if she wanted to feel her and she said no quickly and went to stand very close to her dad.
