Re: frequent colds normal for nursing toddler?
You're not doing anything wrong. Kids are gonna get sick regardless of how they are fed. It's true that breastmilk can protect them from some illnesses but it's because the antibodies you have in your body are passed through the milk to the baby. If you haven't had a particular virus (like a cold, of which there are millions of varieties) then your breastmilk isn't going to help your daughter against that particular virus. So basically you have to be exposed first before you'll have the antibodies in your milk to protect your baby.
One thing to be appreciative of is that you have the best and easiest (IMO) means of calming and hydrating a sick baby. I always loved having the 'magic boob' that would fix any hurt and put a coughing baby right back to sleep at night. Since we weaned a few months ago my daughter has had 2 colds and believe me, it is soooooo much harder to sleep at night when I don't have that to calm her down. I also have to worry about whether she is drinking enough, which was never an issue while we were nursing.
