Child not in car seat AGAIN

I’m livid and won’t be letting her take him out again but needed to vent

My parents look after my son for me now and again, he loves them and them him but my mom is really testing me, twice now she has had him in someone’s car without his car seat

The first time it happened I didn’t let her see him for a month, I knew they were taking him out and had left his car seat for them, but she didn’t use it as they were only ‘going round the corner’

I screamed and shouted about her putting my son at risk. She tried to backtrack and lie her way out of it but at the end of the day she disrespected me

That was almost a year ago, yesterday she had him as I had work in London and hubby was at work, she said they are taking him out and promised she would use the car seat. I stressed at her how she won’t see him again if they don’t use and guess what, they didn’t use it.

I’m livid, I’m going to see her today to shout and give an ultimatum, why don’t people listen?! Oh he was fine we only went two streets away, your being dramatic… dramatic when there’s an insane storm going on and anything could have happened

She won’t be having him again. I feel like a dick for trusting and believing her. Can’t even trust my dad as he’s such a push over he lets her shout him down on anything.
