My son is 4 days old and he's excellent at latching. We gave him a binky 2 days ago and it hasn't effected anything but tonight alls he wants to be is on the boob. He's been on for like 3 hours now because he won't sleep or do anything but cry if I take him off. No one I know has breast fed so I can't ask anyone for help. Does anyone have a little one that does this or have any reason why?
