Hi L.,
Check with the doc to make sure - but I used regular whole milk for the boys, but I bought it from the milk man (Munroe Dairy if you are in the RI/MA area) - then I discovered organic whole milk and now when I can afford to I buy that.
A tip to curb the cost - if you have a Whole Foods near you, their gallons of organic whole milk are reasonable (Under $6.00 A gallon), which for organic is not bad.
But what you can also do is go to the websites of the organic product to see if they have coupons (Horizon, Organic Valley, and several others have coupons) to help with the cost - thats what I do and to me (as a single parent) every little bit helps.
Good luck!! My boys are 8 and 7 now - they still have their fair share of birthday cake and junkfood, but at least they aren't getting the unnecessary hormones..
EDIT: Last I checked this is a forum for other moms to get and give advice about various parenting issues. It is not necessary to bash other people's opinions or views - we all have one thing in common - our children and our love for them. Let's stop the bashing of other mom's advice. It's just wrong.
I wonder what you might think of me? I never breast fed nor will I ever - I must be such a bad parent...
