hi dear, just make sure baby does not always keep head in same position. hand a musical toy/mobile above baby(not over baby's head, but somewhat so that baby looks forward) and keep changing its position...

use a pillow filled with mustard seeds. it helps..

you don't need to hold your baby always. just keep changing the side. it will b ok... or else if you wish you can use mustard pillow... but it will need your supervision.

keep changing babies sleeping position sometime left sometime right , use pillow or u can make a u shape with a cloth to support  baby's head

you can purchase beeds  stuffed pillow from mee mee
