DS never liked them as an infant. He started playing with the ones that dance/play music as a toddler. He just recently (2 last week) started asking to take more stuffed animals to bed with him!
He's slept with one stuffed animal for the past year or so, but was pretty much always kept to a corner. He's napping now with Mickey, Sheepie, Owl, Jellycat Bunny, and a bear!
