Hi pap - I was having the same issues with Hannah. I used to cuddle her to sleep , with no problems - but she did wake through the night looking for me.
I started putting her in her cot and laying down on the floor beside her. I'd just tickle her, or hold her hand. Then one night i told her that I was going to do something - and left the room. She fell asleep on her own. Since then she has slept better through the night. We have had some MAJOR hiccups recently,(mainly her climbing out of the cot) but we seem to have forgotten all about that at the moment. The hard part is that now she doesn't even want a cuddle now before I put her in her cot
