Moving my two year old to a bed - any recommendations for a suitable pillow? A lot of the “toddler” pillows I’ve seen seem too soft and thick.

Red Nose does not have any recommendation for type of pillow for a toddler in a bed, but does recommend to avoid placing a soft pillow against any railing (if using) attached the side of the bed.

Pillows, soft bedding and toys should not be placed against the bed rail. There have been cases of asphyxia in environments cluttered with soft toys
