How Would I Do This?

How would I see if the Children are greater than a certain number. And if they are do something. I just don't know how to check the children:

function PlayerCount()

    PlayerCount = game.Players:GetChildren()

    for PlayerCountLoop = 1, #PlayerCount do
        leaderstats = (PlayerCount[PlayerCountLoop]:WaitForChild("leaderstats"))

        print(PlayerCount[PlayerCountLoop].Name .. "'s Stats")
        print(leaderstats.Attack.Value.. " - Attack")
        print(leaderstats.Defense.Value.. " - Defense")
        print(leaderstats.Agility.Value.. " - Agility")
        print(leaderstats.Energy.Value.. " - Energy")
        print(leaderstats["Power Level"].Value.. " - Power Level")
    end
end

game.Players.PlayerAdded:connect(PlayerCount)
