Team this outfit – fit for any avid explorer – with a map and they’ll be off adventuring in no time. Why not give them a simple sketch of your street so they can navigate their way home (with a guardian’s guidance, of course)!

Teddy Bear

They’ll look so cute, you won’t be able to bear it. Pair one of these hats with some bear-like face paint, fluffy socks, mittens, attach a pom pom to a little wiggly bottom and we’re sure they can provide the grizzle – especially with the number of pictures you’ll be taking!
