My baby is 3 month old. At daytime she take feeds well and pass urine normally like 2-3 times between each feed. But at night time she is taking 90 ml breast milk at around 9 pm then she sleeps for 6-7 hours straight. If we wake up her up then she is not taking feed. also she is not passing urine between this 6-7 hours. What should we do? should we wake her up or allow her to sleep for 6-7 hours??
