My baby is 3 weeks. She's been a fairly typical, uncomplicated newborn until last night when she had diahrrea (if a bf baby can have that!) - very frequent dirty nappies, unpleasant smell and very unhappy baby. She's continued like this today but is certainly improving though her tummy is noisy and she's farting/crying quite a bit.
Last night I had a spicy lentil curry. Could this be the cause? What other foods should I be careful about?
