A. Its fine with any positions Let ur baby to sleep with any of his /her comfortable position. It may be supine, lateral, prone (on tummy) legs up, No need to worry for that positions. Don't change baby's position forcefully if Baby is sleeping comfortably with any position. Feed as per baby's demand only. Exclusive breast feed ur baby till 6months of age Keep a watch on urine output Baby should pass minimum urine 6-8 times per day.
