AIO? Sister in Law told me to get a psychiatrist because I didn’t want my kids to spend the night.

For context, this convo is with my sister in law. My husband had surgery today and she had agreed to watch our kids. When she found out we would be dropping them off really early (at 4:30), she said she wanted us to bring them to spend the night with her. I’ve had issues with her for about a year now. This woman put my children on a Christmas card she sent out without asking us (she denies it in this convo but she absolutely did it and we have a hard copy of it), co-sleeps with my infant in bed with her (I don’t co-sleep and don’t want her co-sleeping), and has generally been trying to stir sh** up for the past year with me (spamming my posts on fb arguing with me, telling me and my husband our house is too dirty) though I haven’t engaged. I said I didn’t want to bring the kids overnight partly because I am very attached to them and I want them home with me (which I think is normal???). And partly because I didn’t want to pack my infant with medical needs (she has a G-tube and takes nothing by mouth) to go stay somewhere when this was asked at 5:00PM. My husband had already arranged for us to take them to my MIL instead once SIL said she didn’t want to do it unless they spent the night. And this convo started with her asking me why I didn’t want them to come over. I feel like the conversation should have ended after I gave her an answer to her question. That should have been it.
