Good pillow
I got the pillow when my LO was about 3 months old. I wish I bought it earlier. He developed a flat spot on his head because he slept only on one side (it was his favorite position). I cannot say that the pillow significantly improved the spot. Although, I think it prevented from getting it worse. The pillow itself is very light weight and breathable (there is a good airflow if you try to breath through it). Because of that, I felt comfortable to leave the pillow overnight in the crib. However, I recommend to follow pediatricians advice not to leave anything in the crib to prevent SIDS.
Good luck!
