6. Sample size- We did a pilot study to see the baseline exclusive breast feeding rates at six weeks in mothers who delivered at DDUH. The baseline exclusive breast feeding rates at six weeks is 60%. Expecting a 10% absolute increase in exclusive breast feeding rates and alpha=0.05 and power beta=80% our sample size is 376 per group. Taking into account the loss to follow up of 20% we plan to enroll 470 mothers per group. So our sample size is 1410 mothers.
