At my sleep and settling session at mother's group last week it was suggested that until 6 months it is fine to settle any way to get you through the night / day. After that it may become an issue and a little bit of hard work for a short time to change the pattern but until then just do what suits you.

I do a combination of rocking to sleep, holding in the HAB, feeding to sleep and putting to bed semi sleeping for Oscar to settle himself. It just depends on the day and his mood.
