Now where is the information backing your stance? Or is it your own personal belief that you're sprouting?
I say your view is an irresponsible one to be putting out their for new mothers who may not know any different. In saying 6 month old babies waking 5+ times per night is normal you are dissuading (probably unintentionally) sleep deprived mothers from aiming higher and getting help with a problem that *can* be resolved.
Most night waking is due to sleep association problems which *can* be fixed (not always).
New mums: please seek assistance, don't be shy just because some folks on a forum whose babies woke 5+ times per night said it was normal.
