Erase the word 'dad' and erase the notion of the traditional family unit?

Is the NHS's decision to reprint pregnancy handbooks to remove the word 'dad' and replace it with 'partner' a much needed step in this multi-faceted society or does it undermine the notion of the traditional family unit? I feel that it is important for the traditional family to be upheld as the ideal in the public arena for fear that in private the very idea will otherwise become obselete. Added to this is the fact this reprinting will cost the NHS £100,000 - £100,000 the NHS could be spending elsewhere.
