Mil and visiting

So my mil is 6.3 miles away from my house or 15 mini drive.I go there two times a week for 2,5 hours.Now that I’m pregnant I feel week often and dizzy I’m scared I will faint behind wheel.But I still go there.For her to say I don’t visit often her grandchild will forget her he doesn’t want to be with her alone.First of all he know she is his grandmother he call her that.Second he doesn’t see her daughter ( his aunt)often but is not afraid of her to be alone so visiting often isn’t reason he doesn’t want to be alone with her.And neither my mom is seeing him often even on FaceTime and she is on different continent.But he is same with my mom when I’m talking with her he will sit on my lap for couple minutes and just walk away.But he loves his grandpa so I think he just doesn’t like her.But 16 years ago she was babysitting my nephew when my SIL returned to work so he was with her a lot so she thought I will bring him everyday to be the same as before.But I’m sahm so I don’t go anywhere because of COVID except for outside for walks.And she gets mad if I don’t bring him if his dad home he is truck driver so I don’t bring him to her house because I would rather spend time with my husband and our son because he doesn’t see him for a week.

Am I wrong for this thinking?

Also my mom didn’t see him since he was born because she couldn’t get the visa and I couldn’t travel because of the Covid and the baby is 13 months old.

And if my mom is here like living here in her house I would be same with her as I am with my mother-in-law there would be no difference. Also my mother-in-law can always tell her daughter to bring her here but she doesn’t want to say anything to her.
