Hello, I have a 12 week old baby boy, turning 13 weeks Sunday. He was a very content, happy baby until the past ten days. He is very unsettled and crying when awake. He will only settle for me and not my husband. I'm becoming fearful to leave the house as it seems to make him worse. I really have no idea why this is happening, I'm feeling a bit helpless, am I doing something wrong? Anyone else experiencing this ?
