Right around 11.5 months to almost 13 months my daughter started cutting all 4 remaining front teeth. Then starting at 15 months for another 4 weeks she cut all of her first molars. So it’s possible it’s teething but I would have him checked out. It could be an ear infection associated with teething or something like that, and for me I’d just want to know for sure that everything is okay. Good luck!!
