Sleep Crutches

As

What does your baby use to soothe themselves to sleep? In addition to a bedtime routine, my son needs to feel and smell my pillowcase. I nurse him in my bed and transfer him to the crib after hes asleep. This is a pain but it works, I am considering putting a small (11 inches),firm, decorative pillow in his crib so he can play with it when he wakes at night but I'm so nervous. Does anyone use a baby pillow?

Hes 8 mos old, cruising around by holding furniture. Is it relatively safe?
