I had seen this on mommysavers!
Mine was for 2 Adults and an 1 year old(even though my little one is 8 months):
estimated $125.36 per week for your household
estimated $543.16 per month for your household
I spend anywhere from 120$-140$ a week! Even though I've gone over on my budget this month. :( I've decided to kick it up to 270$ for next month. Hopefully that'll make me feel better and I'll work my way down from there!
