i would think thats great. We spend $150 a week (not including formula and nappies) and there is just the 2 of us. My sister has 2 girls and spends about $180 a week and my other sister has 6 in their house and spends $200-220 a week.

If you break that down... its costing you $140 a week for all that.

as for ideas of how to reduce it.. im not sure. Mayb buy in bulk from the compaines.. such as spc etc
