It is advised to give your baby Ronalac® LF for at least 3-4 weeks and you may extend for 8 weeks. Even if the signs disappeared in the first three weeks, you should keep giving your baby Ronalac®LF. If you switch your baby to back to the regular formula before the 3 weeks, the probability of the recurrence of the symptoms is high.
Furthermore, it is important to convert your baby to the regular formula, Ronalac® 1 or Ronalac® 2, if your baby doesn’t suffer from congenital lactose intolerance. Lactose is vital for brain and is considered as a source of energy for infants.
You should always consult your physician before switching from and to any formula.
