What colour should 3 month olds poo be?

[KatyJ26]

Hoping you can help me here - Hoping someone can tell me what colour a 3 month olds poo should be? They are formula fed. Slightly concerned the baby may be being overfed

Anyone? Just a one word answer would do me! (shameless bump! )

Pretty much any colour is fine EXCEPT white. White can indicate a liver problem and should be checked ASAP. Brown through green to yellow is pretty normal.

ok, so maybe not being overfed then ... it was very very dark, black almost, but greeney too if that makes any sense
