Her First Sentence .." I like this"

Last night, we read 2 storyboooks.
One was "Ten Little Toddlers" and the other was "Dr Seuss's Mr Brown can Moo, can you?". I held the 2 books in front of her and asked, "Which book do you like better?" She pointed to Ten Little Toddlers and said her first sentence.." I like this".
I asked her to repeat it and she said it again. For the past weeks, we hear just 2-word sentences from her, mostly "I want" or "Give me" . It's such a delight to hear her say 3 words at a go.
This morning, Thaleia said another sentence, "I want Zoo"..asking us to play one of her favourite dvd which shows the world famous San Diego Zoo.
We're trying our best not to let her stay in front of the TV but it is tough!
