I know Mumsnet isn't a monolith but I've found that whether or not a child is seen as a choice depends on the context. In benefits threads they are often referred to as such, with parents 'making taxpayers pay for their choices'. Whilst in threads about children's noises disrupting neighbours night after night it's just what babies do, not a choice the parent has made knowing it is likely to disturb the neighbours. Is this just a case of different people responding, or do you think (some) people have (some) moral incoherence on the way children are viewed.
