and actually some areas are actually designed for the over 4s.
So taking that into account giving kids of 7 and over the evils and tutting when playing quite happily on equipment at the older end because your pfb is on the same equipment is a tad precious and actually not very nice.
If you don't like older kids engaging in loud energetic play remove your toddler and take him/her down to the large amount of play equipment designated for younger children.
Also expecting a large number of older kids to queue for a veeeeery long time so your pfb can spend ages being lifted step by step up a ladder is a tad selfish when it's the only slide for older kids and you have 3 other toddler slides to choose from!!!!
Just sayin.
