Three-month-old babies may often experience nausea and vomiting due to excessive feeding, unpleasant flavors, messy or unclean diets, and other reasons. Here are some possible causes:

1. Excessive Feeding

Newborns have limited digestive systems. If they are fed too much, it can lead to indigestion, which can cause retching in infants.

2. Unpleasant Flavors

As babies grow older, many parents choose to introduce formula or rice cereal. If babies retch, it is often because they dislike the taste.

3. Messy or Unclean Diets

Babies have weak immune systems. If care is not taken, messy or unclean diets can lead to gastrointestinal issues and nausea. When a baby experiences nausea, it is recommended to give them warm water, improve the types of food they eat, and try to feed them bland and digestible foods. When bottle-feeding, the nipple size should be appropriate, and the nipple must be filled with milk to avoid sucking in air.

If the baby is teething, a nipple with larger holes can be used to reduce pain caused by sucking. After feeding, gently lift the baby, place their head on the mother's shoulder, and pat their back to help expel trapped air from their stomach. Avoid frequently changing the baby's position after feeding, change their diaper before feeding, and do not change it after feeding.

General Advice

Nausea and vomiting in three-month-old babies are generally caused by indigestion. At this time, parents should encourage their babies to drink more plain water, as it can promote metabolism. Additionally, babies should be fed more vegetables and fruits. If the baby is breastfeeding, they may need to reduce their intake. If nausea and vomiting are severe, it may be best to withhold food for a while and seek medical treatment. During treatment, it is important to keep the baby's stomach warm, especially when sleeping at night during the summer.
