We have just bought a new tent and booked our first "proper" family camping trip 
DH and I have done long weekend festival camping most years since we got together a decade ago, and for the past 6 years have had DC with us too, but this will be our first long trip and on a campsite rather than at a festival or my mum's garden.
We've booked a fortnight in France, staying at three different campsites (first one really just to break up the journey a bit, then longer at the second two), going more or less down the middle of France as far as Le Puy neck of the woods. First two campsites are chilled/nature-y with communal campfire, woodland, and Loire to paddle in, last one is more lively with kids' club, water slides etc. We're going end July/start of August, so hoping weather will be decent.
DC will be 6, 4 and about 3-4 months.
New tent is massive and we have airbeds, bedding, water carrier etc. We have an Amby Nature Nest hammock for the baby so will probably either use that or co-sleep (camped with DC2 at a festival when he was 3 weeks so not too worried about camping with baby).
We have a fairly shit gas burner to do water for tea and coffee but not really planning on cooking - thought we could get away with fruit and croissants for breakfast, sandwiches/cheese/ham/fruit for lunch (we'll have a fridge at two of the three sites) and then probably eating out in the evening (justified by cheapish option of camping over s/c). Also have a storm kettle which is good for hot water.
Was planning on packing clothes in Ikea bags so can fold away/use for laundry, then possibly getting a cheap hanging rail plus hanging clothes storage things as thought they would be cheaper/pack up smaller than a camping wardrobe. Is this a terrible plan?
Anything I've missed we need urgently/any tips (or links to helpful previous threads)/anything particularly stupid I've suggested? Any advice from seasoned campers much appreciated
