Go with Similac Comfort It won't causes Constipation

Thank you for reaching out and providing detailed information about your baby’s feeding and bowel patterns. It’s quite common to see some changes in stool consistency when a newborn starts on formula, and mild straining or firmer stools are often part of a baby’s adjustment to the new feeding routine. Based on what you’ve described—occasional hard stools with some straining but no distress, and still passing stool once or twice a day—I would consider this mild constipation. It’s reassuring that she is otherwise feeding well, passing urine adequately, and not showing signs of significant discomfort or blood in stools. My opinion: It’s normal for formula-fed babies to have firmer stools compared to breastfed infants. Some straining is typical as newborns learn to coordinate their bowel movements. If your baby isn't excessively fussy, bloated, or having very infrequent stools (less than once every 2-3 days), this isn’t usually dangerous and doesn't necessarily require an immediate formula change

Monitor for other concerning symptoms like persistent crying, vomiting, blood in stool, marked decrease in wet diapers, or refusal to feed. Ensure you are preparing the formula exactly as per guidelines—too much powder can make it harder to digest. Gently bicycle her legs or give her a warm bath to help with bowel movements.

Special formulas like Similac Comfort or NAN Excella Pro are designed to be gentler on the tummy and may help some infants with ongoing issues. You may consider switching if hard stools persist for more than a week or worsen, but often constipation resolves on its own as the digestive system adapts. If you have ongoing concerns or the baby’s symptoms worsen, please schedule a consultation so we can provide tailored care.
