In a word, no. If the baby is getting constipated you should try another formula. "Gold" formulas are known for causing more constipation problems than non-gold formulations and S-26 also has a reputation for causing constipation. Obviously this depends on the baby...S-26 is a very popular brand so many babies plainly cope fine. My own DD has NAN Pro Gold with no issues.

If constipation problems persist talk to your MCHN or go to the doctor.
