My DD is just now turning 15 months. After another brutal two weeks of teething, she has four molars. She got her first tooth at about 4 months... they came in steady sequence after that and she had 8 teeth by 9 months. So she now has at least 12 teeth (it may possibly be more? She is sleeping so I'm not going to go wake her to check!). They bother her relatively often, she will chew on her finger or ask for a toothbrush and chew on that. I know how she feels.. I have gotten 3 of my wisdom teeth since she was born!
In comparison, my DS was 11 months when he broke his very first tooth. And he was nearly 2 before he was getting molars. I know DS was perhaps a little late with his teeth, but it seems DD is VERY early.
Is there something in particular .. hormonal, diet, ? etc? that causes teeth to come in.. or come in so rapidly?
