Don't they just grow up to be big dots that you have to do everything for?...
My little lad is just over 2 now. Proper cheeky little monkey (in a good, cute way!) I love the fact you can have proper conversations at this age & he tells me what's he's been upto at playgroup etc.
He also know how to put his fave DVDs on using my PS3, that's my boy, a geek in training!
EDIT: In the spirit my avatar is him on his 2nd birthday enjoying some 'caaaaaaaake' (his words not mine)
