Hello! my baby boy is 4.5 months old. From past couple of weeks he has been very cranky and irritated most of the times in a day. Few things we have been observing are: # He gets his motion mostly green in color and motion occurs after 4-5 days. # He has some issue with his gums as his put his hands inside his mouth in right corner n when we try to massage his gums he bites very hard. does not take teether. # drooling is there too. # hods his left ear quite often. # stuck out his tongue. # cries very hard with tears. pls suggest what are these signs for. Thanks
