After wake up in the morning time vomiting.

A. There could be several reasons why your toddler is vomiting upon waking up in the morning: 1. **Gastrointestinal Issues:** Your toddler might have an upset stomach due to issues like gastroenteritis (stomach flu), food poisoning, or acid reflux. 2. **Motion Sickness:** If your toddler is prone to motion sickness, the change in position from lying down to standing up upon waking could trigger vomiting. 3. **Morning Sickness:** Although rare in toddlers, morning sickness can occur due to pregnancy or other hormonal changes. 4. **Overeating or Eating Before Bed:** Eating too much before bedtime or having a late-night snack could cause stomach discomfort and lead to vomiting in the morning. 5. **Infections or Illnesses:** Your toddler could be experiencing vomiting as a symptom of an underlying illness or infection, such as a respiratory infection or urinary tract infection. 6. **Food Allergies or Sensitivities:** Certain foods could trigger vomiting if your toddler has allergies or sensitivities to them. It's essential to observe any accompanying symptoms and consult with a healthcare provider for proper evaluation and treatment. They can help determine the underlying cause of the vomiting and provide appropriate recommendations.
