I know you can't see me but I'm grinning ferociously at your sombre declaration of this being half the size of the last one. You're not talking about Thermarest airbeds either are you. You mean those humongous things that migrants cross the med on.
And you're still looking for microfibre towels!
Seriously, it takes a bit of grit to consider cycle touring with small children. I saw a couple years ago on Arran. A tandem, four panniers, one child seat, one tow-a-long with it's own panniers, trundling along happily. I did admit to wondering where the heck the nappies were stored for the tot in the seat. Actually it was probably in all four panniers.
What are these therma rest airbeds you speak of?
Just googled them... no err no and no no no, I'd want a real bed for that price!!!
I do have a deflatey pump that inflates and also sucks all the air out of the flock matress type airbeds... so they do fold up quite small... the pump, however, is quite large

light but large. I need a good nights sleep to deal with 2 small people on the road and light a fire for my morning coffee....
It is the normal blow up airbed thingies... Mr P still cannot get his head round I do actually have a limit to what I can take.. he seriously asked me last time was I taking the "anywhere bed" with me... err no! That looks like this (but a double not a single)
AND today he tried to persuade me to purchase the "footprint" and the "Carpet" for the tent and got told to sod off!
I am doing really well on the downsizing honest... when we go car camping, we have a 12 berth tent, full kitchen, fire pit, loo & loo tent, anywhere beds, gazebo, table, chairs, heater... plus one time a bouncy castle
Towels.... are just another step in making things smaller... I already downsized to the kelly kettle although I insist on taking some small kindling with me in case I am unable to forage for twigs and stuff.. I do have a tiny tub of vaseline and makeup remover pads that are flat for easy fire lighting, this is still loads smaller than a double burner with grill and big bottle of gas....
The chairs are not coming with us again... I will jettison cups and live with just beakers... plates & bowls are a must... I need a frying pan... but can use that as a pan pan too, I cannot live without my coffee pot... we must at least pretend to wash so I have some small sample size bottles instead of taking huge bottles of other stuff...
I shall get there slowly but surely...
I thinka big 10 Litre thing on the handlebars, 38L pannier on the back and the tent/sleeping bag on top, plus small toiletries in Maggots handlebar bag and we can do just the littlest and me for the weekend

wihtout the trailer... if Squidge joins us I have another 2 panniers so we can do luxury
I am not sure I coudl do proper tour tour yet... more cycle to where we are goign set up tent then go back and forth around that area.... I do not so much like the uppey downey packing business
