My DD will be 6 months old on Fathers Day.
She chews on everything in sight and has recently started enjoying teething rusks.
Yesterday afternoon while she was chewing on a rusk I noticed it became a little bit red stained - I think it was blood.

I had a feel around in DD's mouth but didn't get any blood on my finger. She didn't seem to be in any pain but she was chewing really hard and really getting into the rusk.

Could a bit of blood mean she's teething?

She also chews everything as I mentioned - her hands, toys, bottom lip, bottle teats. She drools all the time, has a rash under her chin (from drooling) Red cheeks, often cries in her sleep lately. Do they sound like teething symptoms? How soon after symptoms start can I expect to see a tooth?
