We're getting quite a few "lost" teddy incidents with dd (2 and a half). The teddy is always right there. To some extent it seems like it could be a "ploy" but she doesn't seek any more attention. Just wakes in the middle of the night crying bitterly, when you locate the teddy she stops crying, barely acknowledges your presence and buggers off back to sleep. Am I mad to think a bedside light might assist? It's hard to imagine how it would work in a cot.
