You're using Instance:FindFirstChild() improperly. It will return nil if the child with the specified name does not exist. child.Button does not exist, so it will be nil, and you are attempting to index nil.Touched.
Additionally, RBXScriptSignal:connect() is deprecated, prefer RBXScriptSignal:Connect().
Well, I would assume that child is in fact not nil, but child:FindFirstChild("Button") is nil. Double check that.
Btw, you can do something like this:
if child and child:FindFirstChild("Button") then
child.Button.Touched:Connect(function(hit)
--stuff
end)
end

When I change it to WaitForChild() , then it doesn't trow error, but script freezes. Is there any way to make script ignore line if WaitForChild() can't find child?
You shouldn't throw in random Instance:WaitForChild() calls. If the child doesn't exist, just return.
