My ds is almost 5 months now, and has been a great nurser so far. Just a couple of days ago though, he started doing something strange. He'll latch on and then start crying hard, and grabbing his ear and hair on his left side. My son rarely cries, so I know there's something wrong....I've considered ear infection but he has no fever or any other signs. The only way he'll calm down (and usually go to sleep) is if I put him in his sling and we go for a walk outside. He's otherwise happy! Thanks for any ideas!
