You are right, your baby's main source of nutrition should continue to be her milk.Now that she is 6 months old she can have a little water and tea.I am not familiar with the tea used to treat colic in babies, but would not recommend that you give it to your baby now.It may contain a natural anti-spasmodic treatment.One small bottle of rooibos a day without any added sugar is fine.You can also give her a little water once a day if it is hot.You would have to feed your baby only on water and give her very large amounts to cause the problem known as water intoxication.
