My baby is normally a very happy, fun and energetic baby. He began teething and one tooth came, and he was pretty fussy while that was happening. But now he's literally screaming, yelling, fussing and crying all day long. I don't understand what's happening. It's like he's just in a bad mood almost all day long unless you're entertaining him or distracting him and sometimes that doesn't even work. Did anyone else go through this? If so how long did the phase last? I've literally called off work this week because he was doing so bad. Also we went to the doctor and nothing is wrong health wise thankfully.
