How does everyone split night duties with their partner?

Molly

My baby is a good sleeper with predictable needs. She’s up every 2 1/2 - 3 hrs to eat, and if i hear her stirring, I’ll check the clock and try to prep a bottle of breast milk before she wakes up crying. My husband has been taking one of the night feedings. He’s such a grouch being woken up from a deep sleep OR if he knows he’s got the next feeding duty, he can’t fall asleep.

Sometimes it’s easier to just sleep in the other room with her and take care of it myself, then listen to his crankiness. How does everyone split night duties with their partner and how are they coping??
