Just curious about this as my friend and I have had very different experiences with taking children to stay with grandparents. I know there's no right or wrong answer. We were chatting about this the other day and I'd be interested to know what people think.
My parents have always had a stairgate over the bottom and top of their stairs (although no longer needed since my DC is now 3) and have a fire-guard. My DF also covered the heavy metal fire surround (which is easily tripped over) with foam in case my DC cracked their head open on it and he removes the wobby solid stone ornaments in the garden from their pedestals in case my DC knocks one onto himself when running around. My DM also puts all breakables out of the way (although DC is probably old enough not to touch now) and, since it became apparent that DC can let themselves out the front door, they've put a bolt at the top of the door that DC can't reach. PIL do slightly less but they still have a removable stairgate for the top of their very steep stairs (carpeted, with a solid stone floor at the bottom) and have taught my DC to go down the stairs on their bottom. Also, DC is practically never alone since DFIL is great at following them about and minding them and has been fantastic since DC was first crawling. If I tell him I want to have a sleep or a shower, he'll happily supervise DC for me while I do that.
My friend visited her parents for a few days over Christmas at parents' request. Parents were very excited about the visit. She has two DC, one just 3 and one 1.5. Both very active. Parents didn't babyproof anything, despite my friend asking if she could have stairgates delivered. They had open fires with no fireguards in the kitchen and living-room. Also a dog-flap they leave open during the day to their garden, which is quite big and on several levels with stone steps everywhere and a greenhouse. Their view is that this is fine because it is the parents' responsibility to supervise their children. My friend was on her own with the two kids (husband working Christmas) and no play-pen or anywhere to put the little one (although she did have a travel buggy she strapped them into when she needed to go to the toilet). PIL have quite a lot of breakables and antiques and my friend didn't have a shower the whole time they were there as she felt she couldn't take her eyes off the children. Her parents are now asking her to bring them to visit again but she really doesn't want to take them since it was so stressful last time, even though her husband could probably come this time. However, the parents live over 6 hours drive away so the only way they can visit is to stay with them (or book an airbnb nearby, which my friend is considering).
Is it ok not to stay with grandparents if they won't childproof or supervise the children at all or do parents just need to suck it up and accept that visits may be stressful but it's their responsibility to supervise their kids?
