Hi T., my husband and I went through the same thing with my daughter, she just turned 3 at the end of April, but it wasn't as "pleasant" as just having to go pee. There would be some nights when she would wake up, starting out with a little crying and ending up in a full fledged temper tantrum. We would have to take her downstairs because her room is right across from my sons who is a year old and we were afraid that because she was so loud that she was going to wake him up. I would let her "cry it out" and would keep asking her if she was done crying and as soon as she said that she was I would ask her if she was ready to go back to bed and usually she was. I would put her back to bed and we wouldn't hear from her until the morning. Thank god my son is a sound sleeper, but it happened quite a few times and I too wasn't quite sure how to handle it until my husband and I decided to take something from her that she enjoyed greatly. Each night before she goes to bed she takes a bath, brushes her teeth, and then we read a story and I rub her back for a few minutes before I leave her room. That night that she had her "fit" as I like to call it, I told her before she went back to bed that I would not be reading to her the next night before bed. That night we followed the regular routine and as she was brushing her teeth I reminded her that we would not be reading a story and that if she wanted to have a story the next night she needed to sleep through the whole night. This ploy worked well and she has only had one or two bad nights since then. Because she likes this so much I also use this for other things as well, it seems to work much better than a time out. I hope that this helps and good luck to you!
