Ever since my dd stopped sleeping swaddled (around 8 months old) she has slept with something over her head. At first she would just pull her blanket up over her head. When she was 17 months we bought her this stuffed dog from Ikea for Christmas because she's a huge dog lover and then she started sleeping with that over her head. She falls asleep on her side with the dog perfectly positioned over the side of her face resting on her shoulder. She's nearing 4 1/2 and has done this EVERY SINGLE night (and naps). I'm assuming it's a sensory thing but I don't know what need it serves.
It just cracks me up. She "put my hubby to bed" the other day in her bed and after she covered him with a blanket, she put her doggy over his face! It's adorable but it's just always made me wonder.
Does your LO sleep with something over their head/face?
