My little man is nearly 4 weeks old and today he started to feed pretty much every 1-2 hours (uesaly it's every 3-4 hours) It has gotten to a stage were i had to give him a bottle of expressed milk before bed to calm him down as he was getting worked up like he wasn't getting enough milk from my breasts. Is it possible to run out or has he just fed so much in the day that I'm not processed enough to keep up with the demand??
