My usually laidback, chill, happy 12.5 month old has turned into a clingy, crying, grumpy mess I thought it had something to do with her being sick this past weekend, but the cold seems to have cleared up and she seems (physically) fine. She might be teething again (I have noticed more drooling than usual)... today's just been such a difficult day. She won't eat, screeches and cries whenever I put her down for even a second, wants to nurse every other hour, refuses to sleep, and is just generally driving me completely bonkers.

Is there a growth spurt associated w/this age? What's going on? I'm gonna lose it
