When did you switch from the toddler pillow to an adult one?

[Biloban]

We recently put my 21 month old in a “big boy bed” (full size mattress on the floor) so we could vacate the toddler bed/crib for his little brother who will be ready to move to the crib in a few weeks. He’s been using a “toddler pillow”https://www.biloban.com/collections/toddler-pillow and we have a fairly flat adult pillow on the bed now. Should we switch back to the toddler pillow for a little while longer? He was mostly sleeping on his tummy until a month or two ago when he started sleeping sometimes on his back. He flops around all night but I worry about his neck when he sleeps on his back with the adult pillow.https://www.biloban.com/collections/toddler-pillow
