I'm 23 and I still sleep with my teddy, I've had it since I was born and I honestly would be distraught if I ever lost it. I don't take it on planes just in case something happens and I lose it. I don't go so far as to take it to my bfs, but I do sort of miss holding it - I think its a comfort thing! I've really never had an issue with it and I had it in my room all through uni!
I'm almost 18 and still sleep with a teddy (actually a unicorn, her name's mystic XD)
hmmm, maybe you could replace it with a pet during the day?
If you're just carrying it round the house, doesn't sound bad - in fact sounds like a good idea - I'll have to resist doing that now!
If you really don't like doing it, get somene to ransom your teddy for certain amounts of time until you get accustomed to not having it.
I still keep my favourite teddy at the end of my bed
