I will say about the cot though. We co-sleep - and now we have the cot with a side off, attached to the side of our bed. It's awesome and so technically we are still co-sleeping but she's in her cot if that makes sense.
we do this, and I try to put b00bies away between feeds, incase she isn't really that hungry.
since starting solids DD has woken MORE in the night.
