IMO, no one should travel on a airplane with an infant. As this incident shows, infants are not ready to take on unexpected conditions that can arise when traveling in public. This mother needlessly endangered her child. Also, it is extremely rude to the other passengers. Almost without fail, infants and tots will cry or scream, which irritates most everyone else but is usually ignored by the mother. Once again, nowadays people like this seem to think it's OK to inconvenience the public for their own selfish interests.
