Grand Mum is the only one besides Tilly who knew the truth of Sofia's amulet until the events of Elena and the Secret of Avalor, as she helped Tilly learn about it. Sofia adores her grandmother the Grand Queen of Enchancia. She's also the only member of Sofia's family who knows that Sofia has powers until Elena and the Secret of Avalor, where everyone else is let in on the secret. Unlike the other members of the Royal Family of Enchancia, Tilly has faith in Sofia's self-sufficiency and lets her do things on her own and gave Sofia the job of being the Storykeeper. Sofia and her Aunt Tilly have a very close relationship to the point where Tilly is the only family member that Sofia is able to completely confide in. In return, Amber taught Sofia to become a gentlewoman, bringing Sofia to dress and speak in a more formal manner. This led Amber to become more mature and choose to go on adventures, such as when she and Sofia went on a sailing trip together in " Pirated Away" to see a meteor shower. Later, in The Mystic Isles, Sofia taught Amber that the needs of friends are more important than material wishes. Sofia helped Amber become more mature, flexible, and caring, beginning in The Curse of Princess Ivy, when she taught Amber to be aware of her needs, put herself on the line for her family, and to treat powerful things with caution. After bonding, despite being two different princesses, Amber became happy to help Sofia on princess things and Sofia turned Amber into an outdoors princess. Sofia was excited to have Amber as a sister after moving to Enchancia Castle. Nevertheless, whenever Sofia is mad at Amber, Amber tries to fix their relationship, so they are glad having the other as a sister. Sofia is shown to have a tolerance for Amber's dramatics and annoyed by her tendency for hysterics over trivialities. Amber can't understand Sofia's pragmatism and resents her secrecy despite showing many times that she doesn't deserve Sofia's trust due to showing a shameful amount of disloyalty and rudeness.
Despite finally bonding, the two remain distant due to their temperament. When they first met, Amber took an instant dislike for Sofia due to jealousy. This is because they are so different in temperament. Sofia is not as close to her big sister as she is to her brother. “ Sometimes, being different makes things even better.” ―Sofia. Once Sofia revealed the truth about the amulet, she and Miranda grew closer. This brought Sofia to look to others for guidance, mainly Clover and Cedric. The two grew apart at first due to Miranda now having a new family and queenly duties. However, she is also shown to have more faith in Sofia and encourages her to be herself. She is also shown to not like her daughter's secrecy and tendency to go off by herself and can normally see through Sofia's attempts to give an answer without giving a straight one. Like the other members of the Royal Family of Enchancia, Miranda is shown to not like it when Sofia does things by herself and only lets her go out under adult supervision. However, this doesn't stop Sofia from keeping secrets from her. Sofia is shown to love her mother more than anyone and has a desire to please her greatly. Miranda is shown to care deeply about her daughter and to not take kindly to people hurting her.
It is shown that Sofia and her mother have a very loving relationship. Family Queen Miranda File:Princess-sofia-miranda.png
