DS2 is 16 months, and working on talking, a bit. So far, his words are: digger (pronounced 'dldldldldldld'), crane ('aaaaaay'), duck ('duh') and moon ('mmmmmm'). Ok, he does say mumumum sometimes, but it's more of a command than a word.
I keep waiting for him to learn "more" or "no" or "milk" or "water" or even DS1's name, but no, he just wants to talk about things.
Anyone else got a baby with a weird vocabulary?
