So a few questions here because im a ftm an having my baby soon, i plan to breastfeed an ive not had a coffee or redbull in foreverrr

1. How much caffiene am i aloud to have without it getting to or affecting the baby through my breastmilk an how long does it take to leave my body

2. Would i have to pump an dump?

3. If i have a glass of wine or say alcohol mixed with like a coke or something how long until it leaves my body so it won't be in my breastmilk

(An no i dont plan to get shitfaced drunk 😑 or any of that its just nice to have a drink every once in a while)
