My advice to you would be to get into a more consistent routine. That's absolutely key to things fallings into place. It seems like you're feeding quite often so that makes me think that she is snacking and not taking a good feed. Instead of being on a 3 hour EASY you're doing something like a 2 hour which isn't good for anyone.
If you look in the EASY forum, there are example routines for each age range - take a peek there and that can give you an idea of what other people with LOs the same age find works well.
Also, from 0-3 mo LOs work on ogranizing their nighttime sleep. From 3-6 mo they work on daytime sleep (naps). So right now, she isn't paying much attention to naps yet.
