newborn dont need pillows. just use a cloth diaper as pillow. or if you really want, get babysafe oval shape pillow with a hole in the centre. this oval shape pillow is for 0-6mths babies.
Unless you place yr baby sleep sideways, then mayb can let yr baby hug the bolster. but some bolsters r quite big.
my son from birth until now doesnt use the pillow or bolster. his pillow will endup somewhere else, bolster he dont like, he prefers his beanie.
May i ask who is taking care of yr baby?
