I’m the opposite as we highlight our zip with a glow stick and keep it in reach. Our kids are now 7 & 9 and since they were about 2 we have being putting a small glow stick on the zip so it’s easy to find.
Even now the kids go the bed earlier than us, but they know once in bed they can only come out if something is wrong IE: Feeling sick or need to go to the toilet. (One night while sitting around the fire my daughter came racing out the tent to do a huge vomit, so I’m glad she did as that would have been horrible in the tent)
Once we are all in bed if one of the kids wants to go outside, then they always get me first manly because they are too scared to go outside by themselves.
