Input: 
Backstory: My brother lives with his fiance and their 2 kids, both aged below 5. I'm the godfather to these kids. They live around a 4 hour drive away from me. My brother doesn't live near anyone else in my family who are also around a 4 hour drive away. He does live near quite a lot of his fiance's family. My family live closer to me but none of them drive. My brother is 35, I'm 25. 

What's happened: So my brother and his fiance find it very difficult to get time alone to go out for drinks, time alone etc. His fiance's family refuse to babysit the 2 kids so that they can go out. This has led to him asking me to do it. I've done it 5/6 times in the past. This involves a 4 hour drive each way and all the petrol costs etc, plus all the time i completely lose out of my weekend. He asks me to do it a lot and altough he doesn't always explicitly say it, it's clear he just wants me to come and visit so that i can baby sit and they can go out. He'll sometimes give me a portion of the fuel cost, but i still always end up short changed. 

After like the 8th time of doing this in a just under 2 year period, i really started to get frustrated at it. I feel like it's not fair that i'm even asked to drive 8 hours (there and back), sit alone bored while the kids sleep, pay out of my own pocket for this experience, and lose my whole weekend as a consequence. Out of frustration i simply started telling him i couldn't make it for one reason or another each time he asked. He asked at least twice a month. I've told him i'm not a fan of it. 

So recently, me and my girlfriend planned to go visit Him during a week off me and her had. We would visit on the Sunday. He’d been nagging me to come Saturday and when I said I can’t but we’ll come down Sunday, he says no don’t bother there’s no room to stay. I snapped at him saying I’ve got a life I’m not a baby sitter etc. 

All goes quiet, we don’t go in the end. Until I get a message today saying how I should make more effort to see the boys etc and how I’m
Being a terrible godfather, all that stuff. I kinda snapped at him here.

AITA for snapping at him here? I said that he’s not angry about that, he’s angry because I won’t be on demand baby sitter? 

I want to see the boys but not if it’s on the terms of me being baby sitter every time
At my detriment. Is this bad? I’ve said if
It’s for a day out etc, I’ll always come down. 

refusing and getting annoyed that my brother constantly nags me to drive 4 hours each way to baby sit my 2 nephews
