Everyone thought you were really cute when you were little, didn't they?
I bet everyone spoiled you when you were a little girl.
この場合、次のように言えるかと思います。
ーEveryone thought you were really cute when you were little, didn't they?
「みんなあなたが子供の頃とても可愛いと思っていたでしょ?」=「子供の頃、みんなに可愛がられていたでしょ?」
ーI bet everyone spoiled you when you were a little girl.
「小さい頃、みんなはあなたを甘やかしたでしょ」=「小さい頃、みんなに可愛がられていたでしょ」
to spoil で「甘やかす」
ご参考まで!
