Baby going 4th month old but recently start to drool a lot of saliva , suspect is teething .... also recently keep cry and cry non stop , any mummies got any way to soothe the pain or should i bring baby go see pd

No way. Just have to grit teeth and give them consolation during this period. You can give teether . Some people says cold teether helps to soothe but my gal never like those cold teether. Sometimes I wet a cloth and insert my finger for her to suck and chew on. She happily chew loh hahah
