Inconsolable crying, fever, redness in or around the ear...if you suspect it, your best bet is to get it checked. I've had doctors tell me ear-pulling is a sign and I've had doctors tell me that's a myth and there's no evidence that correlates ear pulling to an ear infection. My daughter had nine double ear infections before her first birthday and got tubes within days of her 1st birthday. Sometimes, she'd even throw up. Often, a baby won't nurse or take a bottle with an ear infection because the sucking hurts their ears. Best of luck momma!
