Yesterday my partner put new batteries in a toy that took 3 button one's. I said be careful as we have a one year old, I took the old one's and checked and it looked like all were accounted for.
I was making the bed tidying up in our bedroom today and I find a button battery at the bottom of the bed right next to our son's crib. I panicked checked packet, the way he'd cut it made it look like only 3 had been taken out but there were 6 taken out..
I've had to search around but thankfully found the other 2 both in the bed near where our son sleeps I'm furious. He didn't think it was a big deal and couldn't think why he had them upstairs, I now feel like I can't trust him.
