I've been busy lately a lot of sick kids. I've only briefly looked at Lnet enough to know someone cursed and Kathy D asked about an extra bolus of antibodies at 18 months. I know of nothing that says there is an extra bolus of antibodies at this age. This is an age for the last set of baby/toddler immunizations (DTaP and polio) so mom might want to BF through this for an improved antibody response to the vaccines. Although there is some evidence that BF babies continue to have better relative responses to immunization beyond weaning.
