Molars erupting under 12 months????

[Pensta]

My bub cut all the teeth babies are supposed to get in the age of 6-12 months by 6 months.....so he has 8 teeth in total.

He has just started grinding and grinding his teeth, is dribbling, is flushed, is cranky, is cranky, is cranky and sticks anything he can in his mouth - on the sides.

I had a look at a tooth eruption chart and it states that babies don't develop their molars until past 12 months. Has anyone else experienced early molar development before 12 months with their bub?

If not - maybe he is part shark?
