Early morning wake-ups - Who's turn?!


How do you and your SO handle early morning wake ups or rare middle of the night wake-ups? Baby is almost 8 months, formula fed, and thankfully sleeps about 11 hours... but on occasion he wakes up far earlier than we would like. How do you decide who gets up, do you have a preset schedule? Or is it always a spur of the moment call? Please don't tell me it's always the mom or always the dad 🙄 We are having a hard time determining a fair way of splitting up middle of the night/early morning baby duty. It's often a "your turn!" Help! Any suggestions that will help keep the peace?
