use musturd pillow...

thank you

I personally think it's myth that you can change head shape....my doctor asked to keep the baby natural and I didn't give her any pillow... she​ is growing fine and has round head... it's belief system...you can try sarso pillow if you strongly believe you should do something for this as mother's vibrations works too much on Babies

just keep changing the position.. or you can use sarso ka pillow.. it's available on first cry and amazon too.. but keep a watch on baby using pillow..
