M.A.
When my son was about 16 months old he started getting ear infections one after the other. After a certain number of them, my pediatrician said to me, "One more & he has to go to an ear / nose / throat specialist to talk about tubes." Thankfully, he hasn't had another ear infection since. Bottom line is multiple ear infections can lead to hearing loss. Has her hearing been checked lately? Is she in school? I know they do screenings at school, but they do so many kids - If I were you, though, I would go to the pediatrician & start reviewing your concerns with him/her & start asking questions & looking for answers. Ask for referrals to specialists if you don't get anywhere.
