White coloured stools are not a very reassuring sign. It could probably be undigested milk but that’s a diagnosis of exclusion. Gall bladder diseases can cause pale coloured stools and I would advice you to consult with your paediatrician for blood tests including
liver function test and probably an USG.
Anemia of 6.7 also needs a proper work up before starting treatment for iron deficiency anemia.

Consult a paediatrician immediately.
