Dry mouth, wet stools

Paige

My one month old preemie has developed a dry mouth. Her saliva is thick and sticky. Her last two poo diapers (she has 1 a day) were much more watery than normal. Cause for concern? She normally eats well. The only recent change is I have begun breastfeeding her more than giving her a bottle (expressed breast milk). A couple days ago at her dr appointment her ear temperature was 99° and she normally has a slightly low temperature..?
