Hi
I noticed you had no replies so ill try to answer a few of your questions and hopefully some of the other ladies will take a look as well cos this reply will bump you up on the board.
First of all.... You are doing a great job! As everyone here will tell you EASY is a routine and not a schedule and you want it to work for you and your LO.
Stick with a 3 hour EASY for now I think it is age appropriate. You would be looking at going to a four hour routine after four months old. In saying that I have only in the last couple of weeks started a proper 4 hour routine with my almost 6 month old. You may need to do a 3.5 hour routine before a 4 or even a combo of both has worked for me.
You don't have to start your day at 7am but it is most common. Again what times work for you. Definitely if your LO is hungry then feed at 5am if this is when she wakes. You can then style to sleep and go for a wake up between 7-8.
Different babies will want to feed at different times during the night. By the looks your wants to feed at 1-2 and around 5 and that amount is normal. I always found there was a 5am waking feed or no feed. Now my DD will settle herself back to sleep and I wake her at 7. You might find your LO will drop feeds on her own as mine did. They do it when they are ready though as long as you are not the prop to fall asleep.
With regards to going out a.k.a ....having a life!! I completely understand how you feel about this. When my DD was a lot littler I could take her out at the start of her wake time and wherever we were at her sleep time she would sleep. Around 4 months this stopped happening or would only do one sleep cycle. I would either accept that was it for that nap and just offer her next one a bit earlier. As they get older wake tines increase to the point where you can go out just in A time and be home in time for a nap. That's what I'm trying to do these days. My LO has a wake time now .
between 2.5-3hrs.
Don't worry too much about feeding as soon as she wakes unless she is hungry!! I would just feed at the 3 hr mark so your day would look more like EASAEAS and that's ok. The main thing is to separate feeding from sleeping
As for you questions on shhh/pat an PUPD, I am hoping another poster could give you some suggestions as I don't have a lot of experience with either as DD has generally self settled from early on.
Hope that this helps you.... You are doing great
