Seriously annoyed

Why is it all I see on here anymore is "don't give your baby this or that it is sooo bad for them read about it blah blah " for example rice cereal in the bottle.. Women saying absolutely do not it will harm your baby !? Well if your doctor tells you to and your baby takes it fine who are you to judge what other women do!? Ughh!! Let people be their own parents without judging them! Everyone does everything different and different times if it works it works!
