<human>: Could you distill the essence of the text into 1-3 sentences?

So, a little backstory. I've known this girl since high school and have always been interested in her, but never had a chance to take her out as she was in a committed relationship. She had a daughter with this dude, which is fine by me. Dude cheats on her and splits, and now she's on her own, and is back in the dating pool. We've been talking for about 2 weeks now and decided to go out today. This would be pretty normal, except she's bringing her daughter along, which is cool, I'm all for it, I've just never been on a date with a girl that has children. I'm nervous has hell. Any advice?
<bot>: girl I'm going out on a first date with has a one year old daughter who will be with us, how should I act?
