First Script (In StarterPlayerScripts)
wood = Instance.new("IntValue")
wood.Parent = game.Players.LocalPlayer
wood.Value = 0
wood.Name = "Wood"
And I want to get this instance for another localscript, Is WaitForChild enough?
wood = game.Players.LocalPlayer:WaitForChild("Wood")
Is this work?

yes it's enough, WaitForChild will yield until the instance is found.
Very, very thanks! This working fine!
