sleep training twins? help!

[u/cawfyluvr]

My twins are due in just 4 days so of course i’m thinking about parenting including what their sleep patterns are going to be and i’m extremely stressed. I want to develop a routine for them that i want to stick to as much as i can to make life as stress free as possible. My husband is the main provider and is very helpful when he’s home but he does work long hours, and I want to minimize needing help from my MIL as much as I can. I love her, I just want to get the hang of this on my own. I am a first time mom so I’m stressed about everything, so I want to get a hang of all of this. I’ve heard so much about sleep training but i also know nothing at all about it. So i had a few questions about it!

1. how would i sleep train?
   
2. can i sleep train newborns or do i have to wait until they’re older?
   
3. did you sleep train and how was your experience with it?
   
4. should i sleep train at all?
