My 2year old has middle of the tongue turns into blue colour within a minute it turns into normal pink

after crying? Any lip discolouration? I can't really make out what you're describing but would wonder if it's a sign of central cyanosis, worth an appointment with your GP

There is no lip discoloration

Get it checked by a Dr, OP.

Actually, Dr is not concerning

Well that's reassuring that your child has been checked by a professional who thinks they are ok
