I don’t know much about almond milk, but my friend was told to feed it to her dairy-allergic son, and he ended up hospitalized for malnutrition. He was only 7 months old though.
Enriched rice milk plus a calcium supplement would cover the calcium needs, but not protein and fat which children under age 2 need for brain development. This can lead to a condition called Kwashiokor’s. I suggest you either use a hypoallergenic formula or see a dietitian to ensure that she’s getting everything she needs.
