Introducing bottle


So this is my second. With my first; he wouldn’t even take a bottle at all so I breastfed exclusively.

This time I would like to give my daughter pumped milk in a bottle sometimes so my husband can also feed her.

From what I am reading, breastfeeding should be well established 4-5 weeks then you intro a bottle. Some of my friends are saying it’s a myth and to introduce a bottle when she gets home, what is everyone’s experience with this?
