My girl passes solid poop everyday for a week already and now second week already. I gave banana, prune, yoghurt etc. Tried everything. But doesn't seems to ease the situation. Give water after solid food. She still feeds and sleeps as usual. 8months old and on formula. Should I visit doctor or continue to give more water?

Solid but what is the consistency? Cos yeah if she has started on solids, stool will also solidify. Bananas harden stool too so maybe that's it. If you give the juice version of prunes etc, go easy, babies may not want water when they grow up on juices. (and gotta think about sugar) :) Some solutions here for constipation: https://sg.theasianparent.com/homemade-remedies-treat-babys-constipation/
