If your 2-year-old child is experiencing constipation, there are a few things you can try before turning to medication. One common cause of constipation in young children can be the process of potty training, which may cause some blockages. Another factor to consider is the consumption of a large amount of milk. It may be helpful to decrease the intake of cow's milk to less than 10 ounces per day and incorporate more fruits and vegetables into their diet. If there is no improvement after two weeks, you can consider using a medication containing PEG3350m, such as Lax-A-Day™ or Relaxa™, which can be found at the pharmacy. Feel free to seek guidance from a healthcare professional to determine the appropriate dosage.
