Frasersmummy - a "full" b/feed for a one year old isnt at all the same as a "full" b/feed for a one, two, three, four, five or six month old.
It's not likely that a one year old would need a "full" b/feed in the middle of the day at that age anyway, and to be clear - we arent talking about newborns, we are talking about 1 year olds wanting comfort - not young babies wanting feeds. Certainly trying to feed a few week old baby (which wouldnt happen - they recommend to have their first set of vaccinations before going swimming anyway - at 8 weeks) would be harder. But that's not what is being talked about, and you certainly didnt say that this is what you were referring to (until now).
I would also think that if a mum is happy enough to b/feed by the side of a pool, in a pool, or around a pool, she'll have already taken into consideration her environment (as far as disturbance etc is concerned) so you neednt worry yourself.
I'm certainly not offended, not least because it takes an awful lot more than that to offend me . I do think that this topic has the capacity of offending some people very easily so it is important to be clear about what you are discussing, and be relevant and correct with any facts. Saves a great deal of confusion (and offence) that way.
