My son is 12 and my stepson is 5. My stepson has lived with his dad and I since he was just 1yr old. The mother lives in another state. We have been living with my mom on and off for the last 4 years and we're living with her now so the kids see her everyday. My mom has always been known as extremely nice, caring and giving but I have been noticing that she doesn't treat my stepson as good as she does my son. She is nice to him and when my son isn't around, she will take my stepson to the store with her and stuff but when my son is around its a different story.
