MIL wants to take DD (2 years and four months) on a day trip to an animal petting zoo. Which would be lovely, except that I have major concerns about MIL's ability to look after a toddler.
MIL does help us out occasionally by looking after DD if she is home ill from nursery, and we are so grateful for this, but even in the relatively safe environment of our home, a few things have happened that have made me question MIL's judgement - MIL giving DD a lollipop (choking hazard), MIL letting go of DD's hand on a footpath outside our house (DH saw this from a window and it was only sheer luck DD didn't run on to the road) and letting her jump up and down on a windowsill (DD fell off and badly bruised her elbow, thankfully nothing broken).
Due to other things that have happened, I suspect that MIL may be showing early signs of dementia. She also suffers from anxiety and panic attacks.
Every instinct I have tells me that I shouldn't say yes to this. DH and I can't go as we'll be working. DD normally goes to nursery full-time but there aren't any issues with her skipping a day, so I can't use that as an excuse. I don't want to upset MIL - she's lovely, and quite fragile emotionally, saying no would hurt her. But I have to keep my DD safe.
AIBU in desperately trying to figure out a way to say no? Am I being an overprotective parent? I don't think I am, as I'm confident in handing DD over to nursery, a couple of friends, other relatives . . . it's just that I'm so uneasy about MIL. DH feels the same - he thinks we should say yes, but doesn't want to.
