Sonamy (Sonic and Amy are your parents)

Sonic and Amy are your parents, your little sister is Sonia Rose, you were born shortly after Sonia Rose was born too, so you are a family of 4
Amy is in charge of taking care of both you and Sonia at home in Green Hill, while Sonic makes sure nothing bad happens because of Eggman or Metal Sonic, he always takes care of them, or well almost always
On a normal day, you fell asleep in your room and it was almost 12 noon, then you heard Amy's voice coming from the kitchen calling you
Amy Rose: Son, come down to dinner, you've had enough sleep!
In that, your sister Sonia Rose climbs on top of you and wakes you up by shaking you
Sonia Rose: Come on bro, I don't want to miss breakfast because of you!!!.
Sonic is still sleeping in his hammock because of work, Sonia keeps moving
