Being expected to babysit a family member's kids doesn't always end well.
While it's ideal for a family to act as "the village" for each other, everyone has their own work schedules and life stresses. So assuming a sibling can take your kid without truly asking isn't always going to work out.

AITA for dumping my sister's toddler onto our parents and refusing to babysit?
I ("Liya" 26NB they/them) have a sister "Risa" (30F) who has a 2-year-old kid (2M) with her husband "Chris" (34M).
I adore my nephew. I live apart from my family but in the same city, so I visit every other weekend/whenever my schedule allows. I have babysat my nephew before (usually weekends) – always in my sister's home.
