Hi All - when did you starting giving your toddler a pillow to sleep on and where did you buy it? My son is 2 years old and because of this dreadful weather, he's been very snuffly the past few weeks. I'd love to be able to elevate his head with a pillow but not sure he'd take to it well and not sure if he's too young to be using a pillow... Just wondered what the other moms out there have done, and when. Thanks!!!!
