there are plenty of ways to bring up children. Being potty trained at 18 months does not mean you were a better parent than someone whose lids werent potty trained till they were 3. some children thrive in nurseries, some hate them, some parents can afford to give up work (or not work) and others can't, some people prefer disposables, some prefer re-useable. Neither one is morally superior IMO. You dont see the same moralizing about, say, period products (which half the population use for about 40 years of their life)between advocates of reuseables and disposables .
There is more than enough guilt that goes with the territory of being a parent without other people poking their noses in and deciding their way is better and you are to be despised as being lazy for not doing it the same
