Increasing of the Milk Production using Syntocinon

Dear Helen

As recommended by you, I try to increase my milk production using Syntocinon. I breastfeed as well as bottle feed my three weeks old daughter.

I would like to know whether Syntocinon increase the milk production permanently or does it only affect the following breast feed? Does it harm the baby and for how long should I keep using Syntocinon?

Thank you in advance for your reply.
