Is he teething?
My son is 6 weeks old and has reflux, gas and colic. He has started bubbling at the mouth (I am wondering if this is normal or the beginning of the teething stage) and while he is asleep has started crying (also wondering what this might be?) I know it seems a bit soon for teething but his gums are very white and he has irritability and has started coughing and rubbing his cheeks alot. Its probably nothing but just wanted your opinions!
