The study was conducted to assess the effectiveness of video assisted teaching programme on knowledge and attitude regarding techniques of expression, preservation and utilization of breast milk among working lactating mothers. Pre experimental one group pre-test post-test research design with convenient sampling method was used to select 100 sample. Self-prepared knowledge questionnaire and attitude scale used to collect data. The study revealed that mean and standard deviation of pre-test knowledge score was (10.25+/-2.324 and post-test knowledge score was (18.92+/-1.555). The paired t value was 32.65 with a P value 0.000 which is significant at 0.05 level. The study also revealed that mean and standard deviation of pre-test attitude score was (47.58 +/- 3.276) and post-test attitude score was (67.88+/- 2.447). The paired ‘t’ value was 49.77 with a P value 0.000 which is significant at 0.05 level. There is a significant association found between demographic Variable such as number of children (Chi square=15.90, P=0.01) and pre-test knowledge score. Also there is a significant association found between demographic variable such as religion (Chi Square=12.93, P=0.005) and number of children (Chi square=12.01, P=0.07) with pre-test attitude score. There is a positive correlation between knowledge and attitude with r=0.01 p<0.19. The present study recommends that EBM is ideal complimentary food for young babies for their wellbeing as well as mothers too.
