Laura asked if a mom never had rotavirus would the antibodies be in her breastmilk. As a theoretical question I'd say the answer is no. You said youve never had rotavirus? I'd suspect either it was a case you or mom didnt remember or you live in an air tight bubble or you've been living on another planet. Rotavirus is one of those infections that virtually all children get by age 3 years. I also suspect your child has had RSV inspite or youre not recalling it. RSV is one of the infections that should the protection of BF against respiratoy infections. It was done by detecting serum antibodies in 3 year olds. These are the child's antibodies by this age, not passed from mom. This means they had the virus. However their personal history did not give an example of severe infections meaning the RSV was too mild to be remembered. I would assume this could happen with flu and its been shown BF babies can have asymtomatic rotavirus infection. To answer Jennifer, "will I reccommend Rotavirus vaccine before or after babies wean" The recommended schedule is 2,4, and 6 months. It's an oral vaccine. For the typical American baby this means starting while BF (responce is better anyway) and finishing after being weaned. However over the past year my patients seem to be BF longer than about a year ago. Am I doing something right? -Rob PS I got to phone calls today about < 4 week old weaned babies with multiple formula problems. Both moms got informed concent about relactating. I dont think they have real formula problems, formula babies are often gasy and constipated and unhappy.
