Category: Baby > Baby formula. Updated 2026-10-08. Based on 270 counted first-hand reports from Target shopper reviews, Oct 2018 to Oct 2026.

**Question:** Which formula is good for constipated babies?

**Short answer:** Enfamil Reguline has the best record for constipation: 38 of 38 parents said their baby's poops got softer or more regular, and more parents weighed in on it than on any other formula here. The three Kendamil formulas come next, starting with Kendamil Organic Formula at 21 of 27, and Similac 360 Total Care has the weakest record here at 3 of 13. Babies differ, and parents often switch formulas because of a problem, so read these as parent reports, not a promise for your baby.

**What stands out:** Constipation complaints gather on the Similac formulas: 50% of Similac 360 Total Care reviews, 36% of Similac 360 Total Care Sensitive reviews and 32% of Similac Pro-Total Comfort reviews mention it. Among the Kendamil formulas, Kendamil Classic Formula draws the same complaint in 28% of reviews.

## Questions

**Which formula do parents say helped with constipation?**

Enfamil Reguline has the best record (38 of 38), followed by Kendamil Organic Formula (21 of 27) and Kendamil Goat Formula (15 of 20). Reguline is a product name, not proof it will work for your baby. These are parent reports, and every baby is different.

**What do parents say about the Similac formulas?**

They draw more constipation complaints than the Enfamil and Kendamil formulas here. Similac Pro-Total Comfort sits at 15 of 28, Similac 360 Total Care Sensitive at 7 of 14 and Similac 360 Total Care at 3 of 13, and 50% of Similac 360 Total Care reviews mention constipation.

**When should I call the pediatrician about constipation?**

Talk to your pediatrician before switching formulas. Call right away if your baby's belly is hard and swollen, there is blood in the stool, or your baby is vomiting or isn't gaining weight. Parents often switch formulas because of a problem, and what worked for one baby may not work for yours.

**How should I mix formula?**

Exactly as the label says, with the scoop from the can and the amount of water listed. Don't add extra powder, extra water or anything else to the bottle unless your pediatrician tells you to.
