Mom wanting to babysit 😭

My baby is 9 weeks old, I haven’t been away from him at all other than my husband being with him while I go to the store, which has been twice since he was born. My mom practically begged me to watch him on Saturday. She wanted him overnight and I said I wasn’t ready. We agreed on the day from 12-7. But I really don’t want to the more I think about it. One she’s had an issue with drinking. I truly don’t think she would drink around him but who knows. She’s also been judgmental on how I parent because it’s different from how she did it 25 years ago. The more I think about it the more worried I am leaving him for that long. But she would get so angry if I backed out. She overreacts a lot. I know eventually I should let his grandma watch him, I just don’t know if I’m ready. I would like the break but not with her really. I feel stuck. Ugh.

UPDATE:

Thank you guys!! You have made me feel so much better honestly about this. I have strong guilt when it comes to her due to pst issues. I told her she could watch him while we go to lunch down the street, which I am comfortable with because my brother will be there and it’ll only be 2 hours max. Just not ready to leave my baby!!
