Breastfeeding

Now that my pregnancy is confirmed I’m just sitting around creating a registry and doing research (I am only 18, so creating a registry is helping me learn about certain products). So to the moms that have breastfed was your baby okay with switching from breast to bottle on a daily basis? Because I know I won’t be using formula but I don’t want to stress about how my baby will be fed when I’m gone so I’m going to want bottles on hand. And I’m not sure if my baby will turn down the bottles. Also what nipples are the most popular that babies love? And what are great bottles for colic babies. I want glass bottles that have way to release air.

Edit: I don’t want to introduce a bottle for a while but knowing that I’m young and will be back to working after maybe 2/3 months, I just don’t want my baby having nipple confusion and giving family a hard time.
