Or is it still to dangerous???

I can’t remember when I gave one to my daughter probably close to two..

But my son (16 months) has been a NIGHTMARE lately he was sleeping through the night but we recently moved and he still hasn’t adjusted.. he loves to snuggle and pretend to sleep on pillows and stuffed animals so I’m wondering if a very flat pillow would help him self soothe...... I know he technically doesn’t need one and is comfortable with out it but my daughter always liked a flat one or something to snuggle.. any other suggestions if pillows are still to much a danger?
