Toddler pillow? Anyone use it?

I was in toys r us the other day and I seen a toddler pillow, it says for 12 months+

My son is 15 months.

Wondering if I should get it for him? Anyone have one? I’m assuming it would be safe at this age? The only thing is he moves a lot in his crib, but not so much anymore.

But I’m pregnant with our second, so once baby is here I will be moving him to his “big boy bed” so I figured if I started practicing now with a toddler pillow, that may be enough for him to stay on that one side where the pillow is which will help him when he’s sleeping in his new bed...

Thoughts?
