My about to turn 2 year old seems to be chewing on things and biting her toys a lot at the moment. She also tries to bite, scratch and pinch me - mostly when she doesn’t want to do something or is overtired. I can’t work out if this behaviour is just toddler frustration or whether she is getting her 2nd molars. It has been going on off and on for weeks now - some days she is grumpier than others. I can’t see any sign of new teeth but can’t get a good look at the back of her mouth so am not sure. Obviously only want to medicate if it’s teeth related.
