Before
We adopt cluster randomization, and we have 32 clusters. We have 4 treatment arms, Control, Treatment 1, Treatment 2, and Treatment 3, and 8 clusters are included in each treatment arm. The differences among the treatment groups are the period of the intervention. We will conduct the free distribution for one, two, and three months in Treatment 1, 2, and 3 respectively. Since we suppose children consume one package per day, we will distribute 30 packages per month to mothers for free.

After
We adopt cluster randomization, and we have 12 clusters. We have 4 treatment arms, Control, Treatment 1, Treatment 2, and Treatment 3, and 3 clusters are included in each treatment arm. The differences among the treatment groups are the period of the intervention. We will conduct the free distribution for one, two, and three months in Treatment 1, 2, and 3 respectively. Since we suppose children consume one package per day, we will distribute 30 packages per month to mothers for free.
