Quentin's 2 bottom teeth, have multiplied. He now has 4 teeth!
(Oct 4th, 2011, the first top tooth cracked through on (your) top left).
By October 6th, 2011, just 2 days later, both top teeth had cracked through the gums.
And now, (picture taken October 25, 2011), Quentin has 4 chompers almost fully grown in, ready to use, to eat. We've been slowly introducing him foods that are more solid than purée. He's certainly enjoying that more, and actually chews his food quite well now. He'll be eating the same meals as us in no time.
