Babyluv: bout 90% of the time I feed to sleep.. Whatever gets her to sleep works for us!! The thing I Learnt from my big rant thread was never to feel bad for doing things...
If it's using a dummy, who cares...
If it's feeding to sleep, who cares...
Whatever keeps you both happy at this stage should be what you do. She is so little... And you are a brand new mum, like you said trial and error, once you find something that works go with it. It won't Hurt her to feed to sleep. She will learn to fall asleep without it, if you are worried tho, only do it sometimes...
