Finnigan can say "more". I taught him using Mini Melts (those flash-frozen ice cream pearls of yummyness) at the mall. It comes out more like "Mmmmm-oe", and is ridiculously cute.
Finn now has two commands: "Mmmmm-oe", and SCREACH!!!!
Also, he can eat an entire nectarine all to himself. Just hand it to him and he eats it, with little baby micro-bites. That's pretty dang cute too.
