I think your baby is just fine! I had my boy for 6 months all by himself and I'd never really heard him dook, or make much of any noise, but when I got my Albino girl and introduced them? Oh you never HEARD such a dooking fest! :) I was tickled pink to hear him making such happy curious noises! And then of course when we recently added 2 more big boys *laughs* the dooks go on forever *giggles* So don't worry, maybe he knows that you can't talk "dook" back to him and he's just being polite *S* Rae Fiona (the princess and only gal) Faoli (the master escape artist and old gentleman of the group) Soot (the sick baby who's SUCH a cuddlebug) Freckle (I want to be the dominate one...really I do! *chomp*) [Posted in FML issue 3609]
