When she turned 2. I would have done it a bit earlier, but hubby was nervous to give her one (even though she'd sleep on ours when she snuggled in bed with us).
He just got a pillow about 2 months ago. He used to move all over the place, but since I started letting him have a pillow, he stays on it all night.
This is where I’m not sure!! I feel like when he’s one years old he might be ready? He sleeps SO well when snuggling with us on our pillow (but I never had him sleep with it unattended as I’m not sure what might happen so I’m waiting a bit longer). Just wanted to see what you all were doing !
