Sorry for delay Juggler, I didn't get notified of the updates for some reason.
To be clear - my baby will only be drinking milk however, when I have tried to book the package for my wife and I P&O have said (online and on phone) that we must buy the baby the soft drink package (£10per day) which is outrageous...not the price, the fact that a baby should be included in the "everyone in the cabin" rule. One person has said wait til I'm onboard and try and buy it and I might try this.
