<human>: We've been friends for almost 20 years. I want to be Auntie Justtheish, but lately she only asks me to babysit, not hang out. I'm the first call when they want to go out for dinner etc, but the past few times its to come over just before or after the kid is asleep, and she's a good sleeper! She goes down at 7 and is in for the night. They'll plan dinner to be after she's in bed, so I am just there to watch tv in their house instead of my own. I don't wanna. I'm child free by choice. I want to know your kid and have her love me. I want to take her on dates and spend time with them all as a family. My boyfriend loves them too and wants to get to know the baby, but I don't want to be free labor. 

Can I say "I love spending time with you and your kid and would love to spend more, but babysitting isn't really my thing so I'd prefer only when she's awake and you are home too"? It sounds great to me but people with kids confuse me. Having decided to be child free, most of my friends with kids believe full force that their time is more valuable and we plan all things around them. I make so many concessions for them, I don't think I should have to give up evenings to sit at their house while they go out. I can do that at my house! They'll suggest I show up early. Like get there at 5 to play with the kid before she goes down, but then that's like my whole Saturday. So I'm a jerk if I don't come early to see the kid though it's a big time commitment. 

So I just say nothing? Is it rude? I love my friends but I'm not a 35 year old babysitter. And no they don't pay me, that would make it WORSE.

Can you provide a brief overview of the text?
<bot>: friends keep asking me to babysit. How to say I don't ever want to, I just wanna hang out.
