I'm 20 and have a teddy!!
I cant sleep without it, but its not the sentiment of the teddy, i just cant seem to get comfy without something to cuddle. any bear would suffice!
I used to have a dolly, but it was really creepy, so i got a bear instead which isnt as weird ha.
Once i didnt take it when i went away and i couldnt sleep, so i tied my pashmina into a ball to cuddle. I think i just need something to cuddle as i've had it for as long as i can remember.
I used to keep my old bear at my boyfriends, and he got me one to keep with me at uni, and then when we're about to go to sleep i'll cuddle it ha, he used to say 'why cant you just cuddle me', but he isnt small and fluffy and doesnt fit under my chin, but he never minded or took the mick!
