Context - My baby's father left me while I was pregnant, just before he was born.
I really empathized with paternal grandma as this is her first grandchild. She called me a lot before he was born asking if I was ok etc (I wasn't, I was heartbroken). She wanted to come to visit me in the hospital (told her no in advance and blamed their COVID rules limiting visitors, I just had a helper there not a visitor). She wants me to bring baby to her house but I've always said you can visit him here, where I live (due to me not driving post c section etc) . She's pushed for weekly visits since he was born which has felt too much for me, so I have always said 'we can do next week on x days' when she asks to meet, she comes for coffee or we go for a coffee out after a mum and baby class, so she sees us Roughly fortnightly. She asks how baby is and wants to cuddle him doenst ask me about how I am and generally the chat is her bleating on about her friends that I don't know, I listen politely. Anyway, I have not wanted to do grandparent alienation, and baby is still too young to be left with any one, so I've just been putting Up with regular small talk with her while they cuddle. It's not very fun for me. (She doesn't visit at same time as baby's dad as he comes in evening and does bath etc, I don't want her upstairs in my bedroom etc).
That's just to set the scene.
So, recently I organized a christening for my baby and invited my family and friends (baby's father was offered chance to be involved but turned down as he isn't Christian. Only I have parental responsibility as he is not on the birth certificate ). He asked me last minute to invite her as she was apparently very keen to go, so I kindly did, she came, took videos and then left soon after the service. Baby was crying from the start as he'd not napped and had got a bit over tired.
Today, as soon as she saw us she said to baby 'oh, you didn't want to be christened did you' and said how sorry for him she felt when he was crying and thought he was going to drown. I was shocked but told her he was crying because he skipped his nap. We then went for coffee and she said that she's shown the video to her husband and baby's father and it was lucky they weren't there as they'd have stopped the whole ceremony. If she talks like that in front of me I wonder how she would if I wasn't there? I feel this is such a rude passive aggressive dig and she should have been thanking me for inviting her (she didn't and no present) and the implication was that I'd endangered him by having water poured on his head and he'd hated it.
I am so sick of being spoken to like that and honestly don't want to continue being treated like that. I have set this president of fortnightly coffee dates with her and I don't want to do it any more. AIBU to see her less and perhaps say that she needs to see him when baby's dad does? (He won't like that either) how can I work this to her/ them? I have been giving a lot to them and don't really know how to be assertive of my own needs
