Can anyone advise me what the best type of sleeping bag/bedding arrangements are for younger children (ages 18mths, 3 and 5)? We have just been away this weekend in our tent, the elder 2 slept in our old single adult-sized sleeping bags (not sure what their spec is but we were fine in them when we camped in chilly Canada in days gone by) on top of camping mats, and both complained of being cold. It was cold at night (I guess about 5C), and we were only just warm enough in our 2 season double sleeping bag, but even with a cardigan over PJ's the kids weren't. I haven't bothered buying kid-sized sleeping bags so far, thinking they'd be a waste of money as the adult-sized singles are perfectly good, but maybe I'm wrong? Suffice to say, by 4am each night I was squashed in a single sleeping bag with my 5 year old and cuddling up to the 3 year old - no fun! The baby rejected his travel cot outright, preferring to come in with us - he wasn't cold due to the number and variety of layers he was wearing, but maybe he wanted his cuddles too! I'm ready for a good night's sleep after all that!
Kids size ones will be warmer because there is less empty space in them, in the same way that mummy shaped bags are warmer. Can you get to a Decathlon? I think your nearest store would be Sheffield. I'm really impressed with their range of sleeping bags, and the information they have on them. My son is 12 and 5'3"; he has their S5 light in an adult Medium, its really warm, perfect size, and didn't break the bank.
As well as some insulation for the beds, my kids have always had 'camping pyjamas' - cheap joggers and sweatshirt to you and me! Plenty warm enough to run around the campsite in the morning as well.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
