my husband's parents where unaware and using my two year old baby adult Colgate tooth paste for 6 month... I noticed this now only..how I know it's harmfulness effected my baby

A. Obviously it is very unhealthy it has too much of flour and a lot of paste do have a little bit of chemicals which is extremely unhealthy for the child I don’t know how come you didn’t notice it for last six months because kids are supposed to be brushed with a regular toothpaste which is specifically for kids like kids under the brand of Colgate Junior Himalaya kids toothpaste so please change the toothpaste for the child now
