I think around 15 months for the first set of molars and then the second set before her second birthday. Didn't seem to bother her in the least. In fact she had two or three in before I even realized she had them!
He started with the last set of molars around 2 and it was probably 3-4 months before they were all in completely. He did wake more often at night but I don't know if that was teething related or just normal toddler sleep issues.
His were all in before 18 months. He had no symptoms, I just noticed them when brushing his teeth. He didn't like me brushing near them when they were coming in which I can understand as the gums might have been tender.
He's worn an amber necklace since 4 months old and that seems to have squashed all teething symptoms.
My son just turned 3 and the last molar popped through about a month before his birthday. It took months for them to come through and it was awful. Good luck.
His bottom 2 year molars started coming in around 22 months. They gave him a little trouble for a few days, but nothing terrible. He's nearly 23 months now and they're pretty much through. Haven't been able to see if his top ones have come through yet or not.
