This study's purpose was to evaluate an intervention to facilitate grandmothers' knowledge and support of breastfeeding. A pilot study with a quasi-experimental two-group posttest design was used to evaluate whether the intervention made a difference in grandmothers' knowledge, attitudes, and intent to recommend breastfeeding. The 26 grandmothers in the intervention group attended A Grandmothers' Tea program; the 23 grandmothers in the control group received written information. The intervention group had greater posttest knowledge scores than the control group but had no significant differences in attitudes or intent. However, a significant difference was evident between the attitude scores of grandmothers who breastfed their infants and of grandmothers who did not breastfeed their infants regardless of receiving the intervention.
