True, but remember that Skywynne loved Jushtin very much and was convinced that he would be a good king and a great user of magic. No mother who loves her son so much and has great expectations for him is glad of her son's misfortune.



Although it is very likely that Skywynne was relieved to retrieve the wand and the Book of Spells (since Jushtin was not very responsible), I doubt she was truly happy to take away her son's birthright. Until Justin was 14 years old and inherited the wand, Skywynne had enough time to have another child, but she didn't, and she didn't look upset that she had a son instead of a daughter.



When Glossaryck asked if he could meet her daughter, Skywynne replied that she had a beautiful son. She also mentions that she felt she had achieved a lot as queen and waited for Jushtin to become king so that she could retire to the royal vacation home she had inside the volcano. This shows that Skywynne didn't care about Jushtin's gender and just wanted to retire from being queen. She never mentions that she wants to have another child.



I think she, like Marco's parents, was happy to have only one child.



Another thing to mention is the mewmans. They are very traditional and do not like the changes, and I imagine they did not like the idea of ​​having a Butterfly king instead of a queen. Surely they pressed Skywynne to have a daughter, but she didn't consider it until Jushtin left the Book of Spells in the stables.
