After 1yo. My LO actually only started using a pillow after 2, and started sleeping with her favourite soft toy at 18 months
After 12 months. It’s recommended not to give any pillow or bolster for babies below 12 months
After 1 , worry if baby cover his nose when sleeping .. might suffocate
Can give when baby knows how to move it around.
Bb is 9mths now I still not give
i gave after 1 yo
