Advice on going to work at 1 year post baby?

Je

I am EBF my 6 month old baby right now. It’s going well and I’d like to breastfeed for 2 or 3 years then switch him to water. If I go back to work full time when he’s a year old, will he get enough milk and nutrients from the milk if he nurses (3 times) - before work, after work, and before bed? What are your thoughts and advice on the topic? Any and all advice welcome! 😊

Additionally - We are a vegan family so no animal products for us.
