and you think it is normal to start school, at 4, wearing nappies (unless in extreme cases of special needs). No child did so in the 50s or 60s or 70s or maybe even 80s- so why not? Children are no different now, are they? But disposable nappies are just too easy and too comfortable. They are hugely polluting both in production and disposal, and take up huge land space.
Another decade and there will be NO landfill space left- so what then? There is absolutely NO reason for children to be in nappies till the age of 3, never mind 4. And they can wear shaped washable nappies anyhow- no need for disposables. Many towns also have delivery, pick-up, wash and delivery services, which are very reasonable if people would prefer not to wash their own.
