my son was and still is like that. he had real bad ear infections, and we did tubes at age 3. he tubes fell out about 2 yrs later. but he has always had a speech delay, i would suggest getting her in to some speech therapy. my son is now in kindergarden for the second time, and he has to go to resource class. if your ins. won't pay for speech therapy, go to your local school. they have resources to help get therapy. also i do believe it will delay in potty training, atleast it did for him. it took us almost a yr to get it really good. he was almost 4 before he really was good. i think its b/c they can't understand whats being said to them, and they don't know how to tell us what they are feeling. hope this helps you.
