Blowing the budget

Obviously it costs more to run a family with two kids than one. But what I hadn't anticipated was that recently, not at all coincidentally with Little Bro's increased self-assertiveness, our "discretionary spending" has increased: we've suddenly turned into a family that buys two babycinos or two textas where previously one would suffice (and that's despite Big Bro's best efforts at sharing). And it's not going to get any better- we are just around the corner from being a family that buys four icecreams, four meals or four plane tickets. And I won't even start to contemplate what it will be like to budget for groceries for two active, hungry teenage boys!!
