I usually feed laying down so I put her back in her bed once I realise she's finished, I just put her back once asleep, cover her wiht her sheet and blanket and if she stirs a little I put my hand on her, or give her a little pat, just a little reassurance that I haven't gone anywhere. I also curl up near her for a bit (as near as I can get lol without climbing into the cot space).

Does she have a sleeping bag or anything? Sometimes I find Jazz wakes if the sheets are too cold lol and i think a sleeping bag helps, because she's not going from my nice warm bed/arms to cold sheets!
