My cousin's baby started doing that and a few weeks later he was diagnosed with milk protein intolerance. Pood green, no vomiting, unsettled and had very bad wind. All day, not a specific time of day.
Your baby is but 2 weeks old, and generally I would say too young for a 3-4 hour gap between feeding. sure, some can go that long, but I would play it by ear with your baby and not aim towards it, if she isn't ready for it. Make sense?
Between 8:15am and 11am, she was VERY fussy. She was upset while eating and after eating and it was hard to calm her down. She would calm down with holding her or she'd eventually drift off the sleep for 5/10 minutes here and there only to wake up acting fussy.
I do wonder whether the milk isn't agreeing with her. Esp as you say the poo is green and runny. Perhaps lactose intolerant? Perhaps milk protein intolerant?
Hope I don't sound like a broken record.
