Could I just be overthinking or does my mom think my son (Her grandchild) is her son?

Ever since I had my son my mom acts as if he’s her son. Normally grandparents call their grandchildren their “Grandchild” but she says things like “My little man.” When talking about him to others. She says things like “If it’s up to me. He won’t be delayed. He’s gonna be smart and advanced.” As if it’s her duty to teach him and show him educational things. I love my mother. She’s a great grandmother. She was a great mother but when it comes to my son she acts as if she can care for him better than me.
