Problem with tool parenting and finding child in the table. Any help?

The script is supposed to give players only five Tools from replicated storage when a part is touched by a player. The problem is the clone gets added to the Player but the for statement doesn't see it in the table the first time. After the first time the function is fired, then the for statement will see it in the table and add to the amountOfTool variable. Any way to fix this?

local object = script.Parent

local objectTool = game.ReplicatedStorage.Tool

local debounce = false

function givePlayerItem(hit)
	if hit.Parent:FindFirstChild("Humanoid")then
		if debounce == false then
			debounce = true
			local playerTable = hit.Parent:GetChildren()
			local amountOfTool = 0
			local plr = hit.Parent
			for i, v in pairs(playerTable) do
				if playerTable[i].Name == "Tool" then
					amountOfTool = amountOfTool + 1
					print(amountOfTool)
				end
			end
			if amountOfTool <= 6 then
				local clonedTool = objectTool:Clone()
				clonedTool.Parent = plr
			end
			wait(1)
			debounce = false
		end
	end
end

object.Touched:Connect(givePlayerItem)

local object = script.Parent

local objectTool = game.ReplicatedStorage.Tool

local debounce = false

function givePlayerItem(hit)
    if hit.Parent:FindFirstChild("Humanoid")then
        if debounce == false then
            debounce = true
            local playerTable = hit.Parent:GetChildren()
            local amountOfTool = 0
            local plr = hit.Parent
            for i, v in pairs(playerTable) do --IF this is the first click we're not going to see anything because there isn't anything to see.
                if playerTable[i].Name == "Tool" then
                    amountOfTool = amountOfTool + 1
                end
            end
            while amountOfTool < 5 do --No matter which click this is refill to 5
                local clonedTool = objectTool:Clone()
                clonedTool.Parent = plr
                amountOfTool = amountOfTool + 1
            end
            wait(1)
            debounce = false
        end
    end
end

object.Touched:Connect(givePlayerItem)

Your problem is that you were doing this:

Touch > Does the player have tools (on first touch this is obviously 0) > add a tool if we have less than 7 tools > Exit the function

When the logic you're looking for is:

Touch > Does the player have tools? (on first touch this is obviously 0) > Add tools until the player has 5 > Exit the function

You could also try:

Touch > Does the player have tools? (on first touch this is obviously 0) > Add a tool > Exit > Does the player have tools? > Add a tool > Exit > etc..

To answer your other question about how to add the backpack we can do something like:

player = game.Players:GetPlayerFromCharacter(plr)
for i,v in pairs(player.Backpack:GetChildren()) do
    table.insert(playerTable,v)
end

where plr is the character object you had previously, and playerTable is the table you had previously.

version to address your comment:

local object = script.Parent

local objectTool = game.ReplicatedStorage.Tool

local debounce = false

function givePlayerItem(hit)
    if hit.Parent:FindFirstChild("Humanoid")then
        if debounce == false then
            debounce = true
            local playerTable = hit.Parent:GetChildren()
            local amountOfTool = 0
            local plr = hit.Parent
            for i, v in pairs(playerTable) do --IF this is the first click we're not going to see anything because there isn't anything to see.
                if playerTable[i].Name == "Tool" then
                    amountOfTool = amountOfTool + 1
                end
            end
            if amountOfTool < 5 do
                local clonedTool = objectTool:Clone()
                clonedTool.Parent = plr
            end
            wait(1)
            debounce = false
        end
    end
end
