I have a really silly question... How do you know when your older infant is hungry? I am BF my second child(3 mos) and at a complete loss. My oldest nursed all the time. This guy is often refusing the breast and getting very irritable that I'm trying to feed him. He's constantly sucking and chewing on his hands, so that is not a reliable indicator anymore. I get worried that he's refusing due to milk supply issues or reflux, but other times he nurses very happily. I think I might just be trying to force feed him when he isn't hungry. Any ideas?
