HC: you need to write to the chair of your MSLC and alert him/her to the situation, and ask for support at the feedback panel.
Local NCT should help too.
I suggest getting a couple or more of strong case histories together which you can use with the panel - keep them brief and focussed.
There should also be a Maternity Health Improvement Panel (HIMP) though I am not sure if these are statutory and everywhere, or just in targetted areas. Your PCT should inform you of this.
Is there a local bf support goup - I don't mean for mothers, but multidisciplinary professional group? If Baby Friendly has been awarded, then there has probably been some sort of steering group to support the process.
Get your local bf stats - it is a legal requirement to collect them and to record them with the Dept of Health. If you cannot get them, there is a pdf somewhere on the DH website which records all the English PCT bf stats.
I don't know of any new bf initiatives, but if you trawl through the govt. policy documents, like Every Child Matters; the Children and Maternity NSFs (National Standards Frameworks); the Children's Plan; Aiming High; (all govt policy documents and all on the web) you will see bf mentioned in all (I think) of them as something that is important and that all parts of the public sector are charged with supporting and (more importantly) improving.
NICE also has evidence-based guidance on postnatal care which includes bf.
What you also need is research - and UNICEF will have it - to show that bf needs a local lead and some dedicated trained personnel to monitor and sustain improvements.
Hope this helps. Hunker knows a lot about this, BTW.
