Run riot in the under 3s / toddler section and don't say anything.
I'm sick of taking my kids to these places and having to mind my toddler as a bunch of 9 years olds run through the young children's section without a care for the toddling kids and babies they are nearly knocking over.
I get you don't always know where your children are but there are some parents who obviously know their children are in there and who don't say anything, I've even seen some where the parents are in the toddler section with their own young child whilst their older ones hurtle about.
Fuck off and use the section for older kids! And tell your kids they aren't to enter that section at all!
I have older DC that come with us sometimes and they are always instructed at the start that they'll be in trouble if I catch them going in the babies section. Does my head in.
