Hi All,
There are at least two different topics going on in this thread, and--although related--we should probably keep them clear.
1) Giving a MOTHER (for her own consumption) fortified blended flour (or any of the fortified blended food commodities). Can you clarify for us though how you know that “the mother’s nutrition is fine;” i.e., are you talking about micronutrient profile or macronutrient status (like you’ve got her MUAC or BMI or weight/height? Though I can appreciate that if her dietary diversity is quite poor, fortified commodities may be attractive, I would agree that if the mother's weight is good, it's probably not a great idea to give her supplemental commodities that have the main purpose of providing calories. Maybe instead, better to consider small-quantity lipid nutrient supplements, micronutrient powders (if that is part of the national protocols), or multiple micronutrient supplements (sometimes called prenatal vitamins and they may ultimately come to replace iron-folate). Hopefully as multiple micronutrient supplements become the norm, that will be a good option for mothers who are already at a healthy weight. Those amongst us who work on micronutrients or food assistance can advise.
2) Breastfeeding, and how to ensure adequate milk production, for the CHILD's nutrition. On this I would most trust the lactation consultant who's advising on this thread; Pamela Morrison always gives brilliant advice. She's telling us (I believe) that the way to increase milk production is through ensuring the breasts are emptied, through frequent feeds, alternating between breasts (I used to hear "empty one first" but I think she's saying we can be flexible and give the other breast if the baby seems they're doing a lot of work for the milk they’re getting), emptying the breast manually if needed and storing that milk and feeding it to the baby later from a cup (not a bottle).
But if a baby is already SAM/MAM, we should probably focus on addressing him/her being underweight as a primary concern, before worrying too much about the micronutrient content of the mother's milk. In addition to whether baby is getting enough to eat, it's critical to consider why else could the baby be SAM/MAM... I know original poster said there are no medical complications, but illness is an important cause/effect of SAM/MAM. With friends from FCDO and ENN, we developed a diagram (Figure 2 here: https://mqsunplus.path.org/wp-content/uploads/2021/10/MQSUNAssumption-Map-brief_wasting-prevention-case-study_26October2021.pdf) to show the different factors involved.
Side note: if anyone's interested in doing research on the complexities of wasting, we and FCDO supported an ENN-led group to try to come to consensus on what the most important research questions might be: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0228151 .
