My LO is a little over 4 months old and has been extra fussy since last Monday (a week ago) when he had his shots. Well the last 2 or 3 days he has been grabbing at his left ear. When he wakes up he’ll play for about 30 minutes and seems fine then out of nowhere he’ll start crying and being extra fussy and I have to rock him to sleep to get him to calm down. I’m not sure if he has an ear infection or just discovering his ear? Any similar situations?
