how to remove recent child added ?

on my inventory there is limited space but every child added creates a new button... i got a counter that is 24 but i want when the counter reaches 24 it will remove any recent child added until counter is below 24

local P = game.Players.LocalPlayer;
repeat wait() until P.Character;
local C = P.Character;
local gui = script.Parent
local menu = gui.Inventory
local folder = menu.Folder
local KeepHats = folder.KeepHats
local ply = gui.Parent.Parent
local inven = menu.Core
local openclose = gui.Button
local Button = folder.Button
repeat wait() until gui.Parent.Parent:FindFirstChild("Inventory")
function getMyPack()
    return gui.Parent.Parent.Inventory
end


function removeOldOutOfTheWay(objects)
    for _, child in pairs(objects) do
        if child.Name == "Button" then
            child:Destroy()
        end
    end
end

function UpdateInventory()
    removeOldOutOfTheWay(inven:getChildren())
if script.Parent.Inventory.Options.Counter.Value <= 24 then
    local x, y = 0, 0
    local pack = getMyPack()
    local lo = pack:getChildren()
    for _, child in pairs(lo) do

      local  neww = Button:Clone()
        neww.Position = UDim2.new(x, 0, y, 0)
        neww.Item.Value = child.Name
		neww.ID.Value = child.Value
		neww.Class.Value = child.Price.Value
        neww.Parent = inven
        x = x + 0.265
        if x > 0.8 then
            y = y + 0.17
            x = 0

	
end
	
        end
    end
end

local pack = getMyPack()
pack.ChildAdded:connect( UpdateInventory )
