Lol Bindy my third child co-slept with me until he was 2 and a half, and it felt like he was never going to move out of our bed! But he did in his own time. Remember what they say, you don't see 21yos sleeping in their parents' bed, so you know they definitely move out of there at some stage. :P And just because she co-sleeps now doesn't mean you can't 'wean' her into her own bed later. But I reckon just cross that bridge when you come to it.
