My child was given a standard set of outerwear and backpack for a camping trip.  I hand sewn these cute labels from Daiso (comes in pack of 3 labels for $2) on their gear for easy recognition.

Talking about Camping:
// Found this book “Let Them Be Eaten By Bears : A Fearless Guide To Taking Our Kids Into The Great Outdoors” last week, trying to finish it asap.
// And this post on camping in Singapore via here.  We have never done outdoor camping before!
