IMO they only gave a press conference with Leonor because she was the spare at the time - and it certainly was not Chris' idea.
. The whole family has such a weird dynamic. CP is getting way too much attention and way too many public appearances - especially for his "skills". He is treated like an asset but he quite the opposite.
IMO there is only one more royal family with a similar set-up: the Danes. There it makes sense because Frodo is not able to keep the show on the road. IMO it shows that they are not trusting Victoria to be Queen without the help of her "brilliant brother". That secures him a paid job as well - because they need loads of money and are unable to earn it.
Madde initially brought herself in a bad position and can't get out now. Of course there was no need to hold her hand while giving birth - but leaving the country (I never get why the Queen and Kind + the crown princess need to be absent at the same time to go skiing in a foreign country instead of promoting Sweden!) for a week is a bit "unusual". IMO they have no sense of "family" - There are three strong units: Vic + Dan, Snake + Sleezy, Madde + Chris - but they have no dynamics between themselves.
