Sorry to say it but, The reason why I doubt Princess Skyla will be the child of Princess Cadance and Shining Armor because she is part of a baby toy line which sells rainbow dash, sweetie belle and spike as babies when they are not babies anymore and skyla will also lead to too much alicorns and princesses, so I think that Princess Cadance and Shining Armor should either have an earth, unicorn or Pegasus colt instead.
