Why is Nap Time Important? Any parent knows only too well the irritability of a toddler who has missed their nap. Naptime helps toddlers to regulate their emotions, enhances learning and supports better night time sleep. The New Nap Mat from Bloomsbury Mill lets your little one snuggle up at any time and place. With an all-in-one toddler pillow, snuggle blanket and sleeping mat, your toddler can enjoy their favourite bedding design on the go.
