Hi there, great questions....and to start,  my experience suggests that the approaches and strategies will really depend on the local context, local capacity and resources available. I would like to share the link to the Infant and Young Child Feeding in Emergencies Operational Guidance: Operational Guidance on Infant Feeding in Emergencies (OG-IFE) version 3.0 (Oct 2017) | ENN

and also a Save the Children SOP on IYCF-E : Infant and Young Child Feeding in Emergencies (IYCF-E): Standard Operating Procedure (SOP) for Emergency Response Teams | Save the Children’s Resource Centre

The IYCF-E Operational Guidance is really important and provides the gold standard recommendations that we ALL need to consider when designing and implementing an IYCF-E Response...

If you share more details on the situation, maybe we can share some best practices in similar contetxs
