This is my youngest at 7.5 months, got all 4 top teeth pretty much together (obv pic shows her left ones came in a bit sooner than right ones) but had all of her teeth, include first set of molars by her first birthday.
My eldest was a bit getting hers, around 10/11 months when she got her top two.
Dd2 got her fangs before her middle ones too, but there was only a few weeks between so it didn't last long. She got them around 9 months
