Spawn skateboard under player

I would like to know ways in which one can spawn skateboard under player like we see in subway surfers.

My best two guesses are, 1.Spawnning skateboard and then making it child of player. 2.Changing current child prefab of player with skateboard attached prefab.

With first approach ,its get complicated to know exact character's leg position.

What you think is the best way? if you know any other good way then please mention . My hierachy structure is, -Parent (with movement script) - Child (with main logic) - Character model

Thanks in advance
