Creatine is a normal component of human milk. Milk levels of creatine have not been measured after exogenous administration in humans. Maternal Levels. North American and European milk creatine values average about 10.5 mg/L with a range of 9 to 12 mg/L. This value translates into about 7 mg daily for intake via milk for exclusively breastfed infants, or 10% of an infant s daily requirement for 0- to 6-month-old infants. Adequate daily intake of creatine for 7- to 12-month-old infants is estimated to be 8.4 mg. Creatine levels might be elevated in the Indian population, reaching 38 mg/L at 6 months of lactation in one study.[ 7 ] Infant Levels.

“No published information” means the studies do not exist yet — not that Creatine is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
