Thanks girls. I don't think I will say anything as I really don't want to cause a rift and know I would probably hate it if someone did that too directly to me. However I might be a bit more vocal in general about the choices I'm making and WHY. Until now I've just said 'I rock her to sleep' or 'she often sleeps in our bed' but I haven't really explained that there's some good research and theory behind my approach. I might do what Marcellus suggested and just say 'Oh I've been reading such a great book... it really helped' etc. so at least it gives the others the opportunity to know that such info/ideas are out there without telling them that they 'should' take on these strategies.

Just makes me so sad that so many dedicated, educated, competent Mums are still told that this is the only way and often that it's actually good for their child - eg. 'he needs you to teach him how to sleep... this is how you do it'. And, as a consequence, so many babies have to experience this stress. I know some parents choose to do this when fully informed of all the options because of their own circumstances and preferences and I want to be clear... I respect that.
Thanks again for your input.

Out of interest... who HAS said something about someone else's parenting? Why? How did the other person take it?
