Am I wrong ? Just a little rant

Ohkay so my sons great grandma wants to take my son to church I don’t mind but he’s 1 and at the age where he does not listen and just running jumping off stuff I feel she’s can’t watch him in that type of sitting because he’s going wanna run around and she can’t chase him around she’s old she can barely get up without help and I’m thinking about telling her no I don’t think he should go but shes already acts funny with me because she doesn’t see him that much (she lives far) and when go to her house my son doesn’t want her to pick him up ( he’s a kid he wants to play ) but she’s takes it all personal remind you she didn’t even ask me directly if she could take him she ack somebody else to ask me
