YANBU okay maybe just a little bit, but if you are so am I!!!
My DS is almost 3YO and no where near ready to potty train he is having none of it, as it stands we go through about 4 nappies a day average, so that's 56 nappies in my bin by the time it gets collected every fortnight which probably gathers up enough toxic fumes in itself to be damaging to the enviroment as well as taking up most of my bin.
I know cloth for people who don't like landfill etc but my DS has severe eczema and there are literally only 2 brands of nappies which we can use that don't break him out so cloth defo out the window!
But anyway if you use a public bin to dispose of your nappies daily then surely in a way it's helping the enviroment a bit by reducing the fumes from them stenching my bin out? I could be wrong but that's just my thoughts.
As for it being illegal, well DP used to be that guy you see wondering about the streets emptying bins and clearing streets, there are people who use the bins all the time in the town centre people used to come out with their litt;le waste basket bags like a carrier bag full of crap basically and chuck it in the bin before DP emptied it and one of the men who did it was a DI with the local police
So would'nt worry too much about that, just drop one or 2 in a bin so to be inconspiculous (sp?)
