Both of my kids have/had chronic ear infections. DD7.5 and PG should have had tubes, in retrospect. I lost count how many ear infections she had, but about 6+ per year from age 1-4. She was a late-talker and has attention and motivation problems. Who knows what kind of link there is between the two, but I have read enough about it to know that it happens frequently.
Little DS (almost 2) just saw ENT last week for a consultation for tubes due to 6 ear infections since December. We are pushing for tubes this time around. He is also a late-talker, but passed a hearing test last week with flying colours.
I find this thread very interesting.
