Teething?

Donna

My baby is 3 months and she been chewing and stobbering on everything possible since 2 month a recently bought her some teether to see if it would help she sometimes chews them her doctor says she "not" teething but i pretty sure she is

What are some signs her gums are bothering her she not a crying baby she starting to screams if she does have anything against her gums should i buy teething gel?
