Hi
Thanks for your query.
As mentioned by you your child is having loose motions for 15 days.I suggest you to get her re examined by your
pediatrician as some investigations like stool examination will be needed .As she is loosing weight this is not good.Due to
teething there is loose motions because child puts everything in mouth due to irritation of teething.
Give her plenty of fluids,lemonade,buttermilk,rice porridge,banana,boiled potato.
In case of
watery stools oral rehydration also needs to be given.
After consulting your doctor she may need antibiotic if he suspects any infection.
In addition she also needs
probiotic to be given 2 times a day and zinc 5 ml once a day for 14 days.
Monitor her hydration status and maintain good hygiene.
Hope this helps.
Wishing your baby good health.
God bless..
