Teething?

We don't see or feel any teeth yet but she's drooling even more than ever...it's just pouring out of her and she's coughing a little bit...I think it might be the excess saliva in her mouth. She's also not really eating and when she does, it's like a third of what she normally eats. She's also sucking on her fingers a lot and pulling at her gums...and the crankiness is almost unbearable. I gave her some tylenol because she just didn't seem right and wouldn't stop crying/fussing (for 3 hours which is so unlike her!) and it helped for about an hour so I then gave her 2 of the Hyland's Teething Tablets and it seemed to help...She's also waking up during the night which she never does...Hopefully this tooth (or teeth?) will come in soon!!
