Wawa Mum is a chickpea based LNS- Medium Quantity, used for prevention. Comes in 50 g sachets. Comparable to Plumpy 'Doz, Ezeecup, etc.
Acha Mum is a chickpea based LNS- Large Quantity, used for treatment of moderate acute malnutrition. Comes in 100 g sachets. Comparable to Plumpy 'Sup.
Plumpy mum is similar peanut based LNS product designed for pregnant and lactating women. WFP Pakistan has developed a chickpea/lentil based product for the same target group, named 'Maamta'.

WFP Pakistan conducted a community acceptability study with women, comparing Plumpy'mum and Maamta. In the trial, Maamta was better accepted. It could be a cultural preference for chickpeas as compared to peanuts, or the lower sugar content in Maamta. However, results may be different in another cultural setting.

Could you clarify whether you are planning to use this product as a routine supplement or a treatment for acute or chronic undernutrition?

Could someone tell us what it contains (I can't see the ingredients on the Nutraset website) and what the plans are for marketing / method of provision - do others share concerns about cross branding from RUTF - products that all now seem to agree should not be promoted.
