4mths you probably want a bassinet as opposed to a seat so i suggest you buy infant ticket instead of redeeming a seat for his/herself.
You can always buy discounted Y and then call MPO that you have infant and for them to put you on the infant seat. I've never tried it but I would think MPO should be flexible enough to do this, or is there a policy that only pax with infant fare attached can sit in infant seat?
