Hi Sarah, and welcome to BW!
Congratulations on your new baby girl!!
Seems to me that you're setting yourself up for uneeded confusion at the moment. I believe you need to decided which parenting style you wish to follow and then stick to it. Especially if they are contradicting each other.
Now, according to BW philosophy, at 2-3 weeks babies really aren't on a routine yet. They are still getting used to being outside of your womb, eating with their mouths and not the umbilical cord etc. So for the most part, starting EASY now is to get you used to motions of it and to start a predictable pattern. That way your baby knows what to expect and you know how to read her cues better.
So if you do EAES, and she begins to cry, it may be for a bunch of reasons. She may have gas, or be tired, or need a nappy change etc etc etc. Also, having the E before the S, is a sure fire way to fall into accidental parenting. So she may take longer to learn to sleep independently. Do you feed her as soon as she wakes? Maybe she needs a moment or two so she can fully develop hunger and take a full feed instead of needing 2.
At this age, a nappy change is considered A time, so I do NOT recommend trying to keep her up longer during the day so she sleeps more at night. Sleep begets sleep. And an overtired baby will sleep badly both day and night.
Like I said, you need to make a decision in which parenting style you wish to do, and commit to it 100%
