Baby monkey weakens as mother cannot produce enough milk to nourish properly. Without sufficient nutrition, the infant begins to lose strength, becoming more lethargic and vulnerable each day. Its tiny body struggles to maintain energy for movement, warmth, and growth. The lack of milk also affects its immune system, making it more susceptible to illness and infection. The mother monkey may appear stressed and exhausted, unable to meet the demands of feeding. In the wild, this situation can be life-threatening, as survival depends heavily on early nourishment and maternal care. Intervention or environmental improvement is often necessary to prevent decline.
