It sounds like the sort of people use to say (and often still do), if a younger mother dared complain if she was drained - All because 'she knew what she was getting into' when she decided to have a baby, and that 'she knew the dad probably wouldn't stick around, she knew babies aren't dolls'
^The above is no reflection of all or even most young mums! I am one.
Anyway, moving on... Isn't it quite tactless and a bit lacking in compassion to say "She knew what she was getting into!"
