Thank you so much for this article. I wish I had read this 24 years ago! My son was breastfed, but did recieve formula from those well meaning nurses in the hospital. He has had severe asthma and allergies as a child. He is now 23 and is in better health, but as a young child was very sickly and spent lots of time in the hospital. The doctors thought it was strange for a child who was breast fed to have so many allergies and to have such severe asthma. THis helps explain the mystery!
