Bottle feeding with breast milk

Draconia

Can anyone tell me the earliest "age" it is okay to give a newborn baby a bottle with breast milk in it? I was told from 6 weeks, but would like to know if you can safely start earlier than 6 weeks. Experience from moms who are doing this would be a great help to share their story with me.

I feel that the bottle may help with my son's feeding as he is still feeding 15 mins on each breast. I'm not sure if it's because my breast is cold and the milk is cold or what is going on.

He still makes good wet nappies and runny yellow/orange poo.

Thanks,

First time mom...
