It is common for infants to struggle with bowel movements as they are still learning to digest new foods. It is important to encourage them to drink lots of fluids to help soften their stools. You can also try gentle exercises like bringing their knees towards their chest or simulating a pedaling motion. If the issue persists, consider speaking to a pharmacist about using PEG-3350 powder to help with constipation. It can be diluted in a small amount of liquid and given to the baby based on their weight. Remember to consult a healthcare professional for personalized advice.
