hi, my ds uses a pillow now and has done for maybe 3mths and he loves it! He is also a very wriggly sleeper and I will often find him just cuddling his pillow thru the night, but he alsways starts off on it. He will lift his head for me when I say do u want your pillow. Its so cute. It is only a small junior pillow that i got him from Big W for about $5.
He still is in a cot, i no as soon as I move him to a toddler bed my nightmares will start! He will be up and out and into everything!

ps I love the name u have chosen for your son!
