My 11 month old feeder keeps biting me, nothing seems to work. please help!!?

My youngest has bit me a few times when he first started teething. Once he even drew blood. When my son started biting what I would do was unlatch him for a minute and tell him "No biting, It hurts Mummy" in a strong tone of voice. If he continued to bite I would again unlatch and end the feeding with a "Okay, you must not want milk right now". I would offer again in about 10-15 minutes and never had a problem. He soon realised that if he bit me he no longer got milk.
