Not always so.
Our first had a choice between the Dees or Pies (wife and inlaws - not sure how they slipped that past me on the Health Assessment I had them complete) and because he has a brain and is sane, went Dees.
Of course the quiet "Go Dees" on the couch every morning as he had his morning bot and cuddle had nothing to do with it.
(In the interests of fairness, #2 due in 22 weeks will most likely have a choice but mum has been very clear it will be bubs' choice and she won't steer. AND THAT WILL BE A FATAL ERROR.)
