How long is everyone up during overnight feedings? My baby is 5 weeks old and we change him, nurse him and try to give him formula. We're up for an 1-2 hours sometimes. 😣 Suddenly he hates the bottle and cries because he's hungry but cries when you give him a bottle. Right now I've been up for an hour and half...nurses for 20 minutes an hour ago. His belly isn't full, he's awake, won't take the bottle of formula and I'm exhausted. This has been going on for a few days now.
