Swara is now 6 months 10 days old. She is preterm baby blue with 2 kg weight. Then after 2 days of birth she got admitted to hospital for jaundice. Then she was normal. I feed her from bottle. Use lactodex stage 1 .and use lactodex itself from birth as I dint had brest milk. I use mimi liquid and brush to clean bottles and sterilizer for bottle sterilizing .now before 10 days she passed semi liquid stool and it had 50 pus cells and mucus. Doctor here gave antibiotic oral for 3 days and she got admitted on 4 to day and completed dose of antibiotics injections through veins. Then again given oral antibiotics today is 4 to day of oral antibiotics. Yesterday she passed stool only once but today again she had semiliquid stool pass 4 times. What to do now I am worried why is this happening even after maintaining full hygiene.
