4 months - big world out there

baby turns 4 months today, and i can't imagine our lives without her. she is really well-behaved when we bring her out (she no longer fusses in the car seat as long as she is not hungry, hurray!) and we can usually get a decent meal in without having to carry her much. she also isn't scared of places with bright lights or loud music, which is probably because she follows me to the supermarket, library and nearby mall and is used to being in crowded bustling places.
now to get her used to visiting other homes ... she has been generally ok, but dark enclosed spaces seem to frighten her. i guess it is a natural reaction since baby may think of it as dangerous and alarm bells start ringing in her head.
