YABU, but you need better kit. I have been camping regularly for 45 years. Two years ago, we got a motorhome, because my arthritis was making it very hard for me to put the tent up. Although I love the motorhome, I still miss being in a tent.
Your tent needs to be 2-3 berths bigger than the number of people occupying it, so at least a 6-berth for 4 people. It needs a sewn-in groundsheet and plenty of overlap on the doors, to avoid leaks. Some sort of awning will increase the amount of space and reduce frayed tempers.
You need electric hook-up, which will make cooking and hot drinks easier and quicker, and a decent stove.
You need decent beds and bedding. I've always managed fine with inflatables, but they make you very cold unless you insulate under them (some people buy tent carpet, but old newspaper or corrugated cardboard is just as effective, Aldi or Lidl sometimes sell foam-backed picnic blankets which are cheap as chips and work a treat). A good sleeping bag or duvet from home and cheapo fleece blankets will make all the difference, also fleecy pyjamas or onesies.
Camping toilet of some sort is essential if your kids are too young to go to the bog alone in the night. I recommend a "no crapping" in it rule though.
I've always kept camping furniture to a minimum: a cooking stand with shelves beneath, a folding table and folding chairs. All this wardrobe, folding cupboard etc is just more stuff to pack, set up and take apart. A decent sized holdall each for clean stuff and they can get what they need out of that, and a big cheapo bag for all the dirty washing should suffice. I keep all my cooking stuff, plates, cutlery etc in a plastic storage crate which fits under the cooker stand.
Board games, playing cards and story books are your friends, although ime kids are usually so knackered from all the fresh air that they crash out soon after wine o'clock.
