Could be an eczema/ gastrocolic reflux
Hi...My first suggestion for you is to upload an image of the rash
she is having. Skin and eye conditions are best diagnosed only after seeing directly. I suggest you to upload photographs of the same on this website, so that I can guide you scientifically.
I feel the symptoms you quote fit into eczema, which is an allergic skin condition common in this age group. The Loose stools could be gastrocolic reflux.
Regarding eczema - the trick of the management is keeping the skin moist and never allowing it to be dry. For this oil massage
and lotions like Oilatum will help. Regarding cure options - eczema is a sort of allergy
...allergies can only be controlled and can never be cured. But usually kids grow out of it...that is as the age progresses, they become better starting from 6 months.
Regarding Gastrocolic reflux - It is not a diarrhea
and is only a gastro-colic reflux. It is quite common for babies of this age group t pass small amount of diarrhea or loose stools soon after feeds. This need not be treated as diarrhea and especially antibiotics are not indicated.
Unless the kid's having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting
...you need not worry.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. Wish your kid good health.
