Introducing a bottle

De
I've got a tiny stash in the freezer (about 20oz) already because the plan was to eventually introduce a bottle of pumped milk so her daddy could participate in feedings a few times a week or maybe once a day. And so eventually we can leave her with her grandparents if we want or need to go somewhere without her. She's 3 weeks old right now and I was told to wait a month to introduce a bottle or binky. Breastfeeding is well established though and she will occasionally take a binky to comfort suckle. Part of me is really reluctant to give her a bottle though because I really really enjoy breastfeeding her. But I'm afraid if I don't introduce one soon than she will never take one and there will eventually come a time when I will need her to take a bottle.
