Breastfeeding question?

London • 24 years old and a 1st time mommy to a beautiful baby boy 💙 7/14/16
Is it really true that you shouldn't give baby a bottle or pacifier if you plan on breastfeeding to avoid nipple confusion and help with milk supply? I want to breastfeed but after 6 weeks I'll start back working so he'll have to take a bottle but I'm afraid of him getting to attached to the breast and not wanting the bottle if that's all he's use to for 4-6 weeks Just wonder other moms experiences.
