SIL wants to take DD out for the afternoon. How to say no without hurting her feelings

[Wearit]

DSIL very kindly asked if she could take DD out for the afternoon one day so she could spend some quality time with her. I know this is a really nice gesture and DD would enjoy it but I just don't feel comfortable with it.

My reason for this is she sometimes lacks basic common sense. To give an example, we were once going on a car journey and she was in the back of the car with DD. She was very helpfully trying to teach her (aged 4) how to get out of her seatbelt! I had to explain it was more dangerous if she took her seatbelt off without us realising and there was a car accident afterwards. She was like, 'oh yeah!' FYI, DSIL is nearly 40.

She also has a few mental health problems so will feel very rejected when we tell her no, so how do we break it to her nicely?

Many thanks

I was about to post exactly what Dinosaurs says. Or a mall - you could go to the naice shops bliss while they hit the Disney Store, ice cream parlour and cinema.

Yes what Dinosaurs said, especially on trusting your instinct.

When my Niece and Nephew were 2 and 4 I remember my SIL dropping them to my dm's house (I still lived at home), my dm was at the shop 10 mins away, my job was was as a nanny to 3 children at the time. I told SIL who was needing to get away I was staying in if she wanted me to wait with them, her response "no thank you, I don't trust you with my children" N and N are adults now, I don't know them and I don't really mind that they are strangers cunt face SIL hyped them up as another level of special. It goes without saying she doesn't know my DC either.
