My son has nursing bottle syndrome.  What is it? Nursing bottle syndrome i have discovered not many mums know about. In fact every mum i have spoken to hasnt heard of it.  This problem is when your child either feeds from the breast or bottle and falls asleep with the bottle or breast in his mouth.  The child then does not swallow and the teat lay up on the roof of the mouth with the milk, juice or cordial that is in the bottle/breast, causing the top teeth to rot.  I didnt think that this would happen with milk, not thinking about the natural sugars that are in milk. To prevent this i would suggest not letting your child sleep with the bottle in their mouth, my son didnt take the dummy and i thought this was great until i discovered his teeth and no one told me about this problem until i took him to the dentist not knowing what was going on.  I am not a bad mum, in fact quite the opposite cause now he is 3 and every night and every morning when he cleans his teeth i feel guilty about what has happened to him.  So please dont let this happen to you or any of your friends children.  Warn them before it is too late and they feel as bad and guilty as i do every day.
