I used it with dS too from about 3 weeks- and he loved the taste as well.... interesting that you used it for teething too, aussienic.. i didnt realise it was god for the pain releif.. i might try that as ds is now getting the first signs of sore gums and i have used panadol but he doesnt like the taste!
If you read the back of the bottle it suggests it thats why we started using it in the first place.. WOnderful little bottle it is
