DD is 12 weeks old and in the last week has started doing some serious dribbling. She's also just learnt to hold things and shove them in her mouth and now seems to be constantly sucking on something, preferably material (bib/blankie/whatever!) or her/my fingers. She seems to be crying a bit more than normal, especially around bedtime. She's feeding and sleeping normally.
I've read that babies may start doing this around a month or two before they start teething. Is this true, and if so, are we going to have to put up with the permanent dampness and unexpected bursts of crying for that long? Is 12 weeks too young to get a first tooth? I can't see anything on her bottom gum, it's just pink as normal.
If this is teething, is there anything I can do? She's got a good teething rattle but she only chews on it for a bit before she drops it or loses interest.
