My lo is 3 1/2 months old and I have had a rough road. Not with bf...that is going fine but I have been sick with strep throat, an eye infection (3 times) and now mastitis. So I've been on a lot of antibiotics and I feel like I've been taking a lot of motrin and tylenol in my baby's first months of life. Is breast milk still the best thing for her? I worry that all the medication is not good for her and maybe she would be better off with formula. Any thoughts?
