I am finding that Jack still has great immunity from being bfed for 14 months. He very rarely gets anything despite going to day care 2 days a week, and spending time at least every 2 weeks with a friend's DD who is always sick (she was ff). But this season has been so bad that both boys have had an ear infection - the first time for both of them, Jack is 2 1/2 and Thomas is still bfed at 11 months. Like the others have said, I find they get sick less often and less severely but it still happens sometimes. And unfortunately the younger one will be exposed to extra bugs through their sibling. I think you will find though that each time they do get something, it builds their immunity up even more.

I hope they both get well soon for you. It's really hard having two sick at once.
