Am I bad for giving unfair gifts to my cousins?

My goddaughter visited me today along with her cousin my goddaughter is also my cousin. I gave them gifts for Christmas. Also there is also the mother of my cousin 2 along with her siblings. So they are total of 4 plus my goddaughter. I gave them expensive gifts and gave my goddaughter only cheap gift. When they opened it she seemed sad when she saw their gifts compared to her but didn't say a word.. she said thank you tho.. so AITA?
