Hi Maggie,
First thing i want to say never do anything you wouldn't feel comfortable with just because others think you have to. If you are happy with feeding or rocking to sleep then it shouldn't be a prob, only in others minds.

From what I've read and heard CC shouldn't really be attempted in a baby under 6 months. If you are not happy with doing CC anytime I have heard there are some books out there that will give you ideas of what to try without tears, I haven't read any myself as yet but you could ask in comforted sleeping- no cry sleep solutions forum.

My DD is just over 3 months old and we do the same thing she rarely puts herself to sleep and only does if she's helped to get drowsy. It doesn't bother me cause I will feed her to sleep and if I've popped out then whoever is looking after her can rock or cuddle her to sleep so i don't see it as a problem.

And another thing is that maybe as your baby gets older he himself will learn not to rely on you so much for sleep so why go thru the grief of forcing him just cause others tell you what you "should" do. Follow your instincts and do whatever makes you and your baby happy.
