No, I think that baby will be equally baffled. Most children's first words are mummy or daddy, in this case it will probably be "what the f--k"!
I did recently see a US drama series where a certain sexually ambiguous character was always referred to as 'they'. I suppose it's the only non-gender way to refer to them in the third person apart from using 'it' which I imagine they would find offensive. Confusing times.
