julia CHILD

i am watching julie and julia again on my day off. i noticed that at one point in the movie julia had a sad look on her face as a mother pushing a stroller walked by with her child. then later in the movie she is crying when she finds out her sister is pregnant. so i assume julia child could not have children. interesting i did not notice this the 1st time i watched it as i was just starting my journey of trying to conceive in 2009. just thinking out loud....
