Julia is 4 month old now, she is such a happy content baby.
The things she can do:
Babble, lots of different sounds. I like the singing one most.
Tummy time: She can lift her head up very high and quite long time.
Grapping things: especially mummy's hair!
Giggles: When she is tickled on the neck, or we blow rasberry on her tummy, she will make very sweet giggles.
She is sociable, always smile to people.
