pink xuan,
i think you should let her try more semi solid food since her intake is so little.
fumiko,
my boy's poo become not so watery as well. color didn't change except when he ate sweet potato, his poo is more orangey color.
i also didn't "force" my boy to drink water when he's on FM, now he starts on solid, he also doesn't like to drink water, only drink about 30-50ml after cereal/puree.
mvh,
ya banana may cause constipation. i read from somewhere that fruits start with "p" will help in passing motion, like pear, peach, plum, prune etc.
