i have a problem with my two & half years old baby while he is watching the tv he stands directly infront of it and if i call him almost 100 times he never answers, i have tried almost evrything with him and didn't work.
its really common in todlers its called selective hearing lol
seriously tho if you are concerned about his hearing take him to your health visitor or GP they will do a simple pain free audio test and refer him if necessary xxx
