They understand so much don't they??!! My 16 month old will start walking to the garage and waving and saying "bye bye" when she sees me pick up my handbag and keys - she knows this is what mummy does when we are going to leave the house!
She says about 15 words - Mummy, Daddy, Pip (our dog!), Poppy, Nanny, duck, teddy, shoes, fish, clock (her first word - though it sounds more like *** when she says it, hahahaha!) no (she says that a lot), yummy, apple, na-na (banana), hat. And she can make some animal noises too, like woof woof, quack, meow, etc.
It's only been in the last 2 weeks that her vocabulary has just exploded, she has started saying about 5 of those words from the list just recently.
I have noticed with my DD that she has spurts of development - it will feel like ages since she has done something new, and then all of a sudden she has a spurt where she is suddenly doing heaps of different things! I love it, it's one of the best parts of being a mum is experiencing your child do something new for the first time wub
