Haha, so cute!

DS calls me 'mimi' instead of mummy - no idea why, but he always has.
For drink he just makes a slurping sound, and for sleep he makes a snoring sound, lol.
Yogurt is 'gogo'
He calls my brother (Daniel) 'Doug' - which we like better and have now adopted!

There's probably heaps more, but I can't think right now.
