This was our first stay (at New Barns Farm in Bedfordshire), and while we enjoyed it very much, we did find it quite hard work with two small children (1.5 and 4.5). Hannah and Will, the farm owners, were very warm and welcoming, and I couldn't fault them.
DS1 loved the bed in the cupboard, and we hired a travel cot for DS2. They, of course, adored being able to run in and out when they liked. We knew in advance (from online searching for tips) to get the stove started as soon as we arrived, and my DH managed that quite easily. I was paranoid about the boys burning themselves, though, so we got a couple of fire guards (which were available to borrow from the farm). This was better, but I was still worried. The tent was really lovely, with comfortable beds, although we did get a lot of flies as we had the front flaps open most of the time. There were also a lot of creepy crawlies that my husband had to dispatch before we went to bed. My DC slept very well, even during the wind and rain one night, which were incredibly loud in the tent. It was difficult not having hot water at the ready, especially first thing, but we managed. The honesty shop, where we could pick up our pre-ordered baked goods for breakfast, or other things we forgot, was very well stocked, but a bit of a trek, especially for the boys.
There were lots of places for them to explore, but not on their own, so we took them to play in the hay in the barn, visit the sheep and chickens, see the horses, and walk in the woods. There was also a tour of a dairy farm available (£10 per child, although they didn't charge for DS2), which was fantastic, and well worth the effort to go (only a 10 minute drive). We visited the nearby country park as well another day, which was lovely.
We ordered a prepared meal our first night, which arrived steaming hot and was very nice, but too much food for us; we just kept it in the cool box for lunch the next day, though. Pizza night on the Saturday was fun, but a bit chaotic, as we would prepare one pizza, get it into the oven, then be in the queue to make another when our first one came out of the oven, so there was a lag between getting them all for our family. Unfortunately, it was very windy and started raining, so we didn't get to mingle with the other campers as we would have hoped. We ordered a bbq box for Sunday night, and it was enormous - enough to feed 6 hungry adults. Far, far too much for 2 adults and 2 small children. It would have been nice to have the option of a smaller box, and to have a bit of choice - we got more pork than I would have liked (kebabs, ribs and sausages), so much of it went to waste, and no chicken. The rest was minute steaks and burgers, which were lovely. It was very difficult to bbq without proper utensils, and I really think they should have been provided. There were also no condiments provided, or available in the honesty shop.
There were 2 boxes of wood and two firelighters provided, which I thought was a little mean, but we foraged for wood for our bbq, so managed to stretch the wood out.
The showers were fine, with warm water, but obviously, not so good for the DC. We managed to find a system, with me washing the boys one at a time while DH stood outside with towels, but it was difficult.
Overall, our 3-night stay was a welcome break, but we were glad (DH) and relieved (me) to be going back home.
Top tips: bring a lighter, as the matches won't last long if it's windy. Some newspaper is also really useful for the bbq, as is foraging for your own wood (although not for the stove inside). The cool box won't keep things cold, so don't bring too much perishable stuff. Bring condiments if you're planning to bbq! We found having kitchen roll extremely useful. A torch is also necessary, as the lamps and candles aren't nearly bright enough for reading inside. If you're only a family of 4 (and not particularly good eaters), it might be worth going together with another family for the bbq or one of the meals, so the food doesn't go to waste.
