You say the attitude of others put you off using cloth nappies but then summarise that nappies shouldn't be reusable at all, which suggests that really it was your own attitude that put you off
A number of issues put me off cloth; the attitudes on certain cloth groups was merely one factor (I listed most other factors but may not have mentioned the leakage problem and how many brands I tried attempting to find one that was a good fit. Whereas Pampers fitted instantly and there was no extra washing, drying, wet bags, no need to buy brands ‘cut for cloth’ etc). We had a nappy bin that sealed each disposable nappy so no smell escaped, and it was emptied daily.
If someone finds cloth suits them and their baby and family, great! I have nothing against cloth if people prefer it.
In OP’s case it sounds like her husband is doing all the washing and drying, so if she/he switch to disposables at some point eg when baby weans they shouldn’t be made to feel guilty by the pro-cloth brigade.
Hospitals may not use washable sick bowls but they certainly use washable sheets, blankets, gowns and towels. And there will have been plenty worse than sick on those. Do you suggest they are just binned after every use? The world is not sterile, something that has encountered bodily fluids doesn't need to be immediately thrown away
Sheets, blankets, gowns and towels are laundered at very high temperatures, in industrial machines with strong chemicals. Sometimes the above are indeed binned (eg when covered in bodily fluids or stained badly) and if a patient has an infectious disease all their linen goes into a biohazard bag to be dealt with separately.
All our sick bowls, commode buckets, wash bowls, and other single-use items like needles, speculums, IV bags, tubes, gloves, aprons, masks etc are single-use. Re-usable items can be chemically or heat treated to sanitise them so there’s no risk of cross-infection.
I think single-use nappies in nurseries or childcare settings makes sense, as soiled nappies sitting in wet bags on pegs all day can leak and smell (sure some don’t, but some do!) What if a child has rotavirus or infectious diahorrea and the soiled nappy is dripping through the bag onto the cloakroom floor? It doesn’t take long for other kids (or staff) to step in the drips and spread it.
