Bottom 2 teeth came through about 2 weeks ago and she was a bit unsettled during that time. Last few days she's been off her solids although taking milk as usual, refusing solids though. Also keeps sucking at my arm or leg or whatever bit of skin she can reach and usually after milk she does this, and this is new for her to suck like that. She's more irritable too. Is this teething? Is it bottom teeth growing or is it new teeth coming through? I can't really see any sign of a tooth about to pop through yet
