All the missing kids and their siblings If a kid isn't on here, they're an only child
Lulua had an older sister and a younger brother. She looks up to her sister, which is why she started wearing a hijab so early.
Tyler had an older brother he loved very much. He now loves Danny, because he's a replacement for his brother
Mia had a newborn baby brother which she didn't like very much. He'd grow up upset that he never really knew his sister.
Alexis had an older brother who hated her, and a younger brother who loved her. The youngest had to get his arm amputated at birth, due to a huge tumor.
Sophie had many sisters and a baby sister on the way. None of them liked her very much
Samantha also had a lot of siblings lol
Gabriel had a little brother
Jeremy had a little sister. It's why he's so close to Susie. He misses his sister a lot, and Susie reminds him so much of her
This one is actually canon. Susie's sister was very serious all the time. She was often annoyed by her sister's bubbly personality. But now that she's gone, she misses her dearly.
