I learned a new word. It's "broody".
It means when somebody really really wants a baby. I realized we have no translatable word in American English for that feeling. We just say, "she really wants a baby". But the feeling when you might walk by a baby store and feel that you want a baby -- that's called Broody.
I came across the word because Mineska and I were walking by a baby store and she asked if I was broody.
I think the word I have used in the past is 'lactating'. Like if I was walking by that store with somebody, I would have said, "Are you lactating?" But that's kind of vulgar.
