A 28-year-old ASHA worker in a rural district of Maharashtra identifies a 2-year-old child with severe acute malnutrition (SAM) during a home visit. The child weighs 9 kg (expected weight for age ~13 kg) and has bilateral pitting edema. The mother reports the family lives below the poverty line and cannot afford adequate food. The ASHA worker has referred the child to the Primary Health Centre. What is the most appropriate immediate next step in the management of this child under the ICDS framework?
