Good morning mommies! The child has had loose stools with a slight odor for the past couple of days and has suffered greatly from sleep deprivation. He wakes up every hour, cries, then calms down after feeding, and falls back asleep. After 40 minutes, he wakes up again and cries, then throws up a lot, and coughs afterwards. The pediatrician said it's within the normal range, but I can't watch him suffer anymore. He doesn't sleep properly at night, only on his mother's arms during the day. Can anyone tell me what they did when their child went through this?
