Teething. It's one of those words you hear before having kids and don't pay much attention to. But when babies start teething -- hooo boy, it's impossible not to pay attention to.
Some little ones breeze through teething with nary a whimper in sight, but others are constantly uncomfortable and practically impossible to soothe. It's heartbreaking, frustrating, and it can actually be kind of confusing (is it an ear ache or teething?). Here's everything you need to know about teething from first signs to when to start brushing.
