Gosh, so many of the points in your original post struck a chord with me - as well as some of the responses!!!
My MIL fed her babies carnation milk (yes, evaporated milk) and water and suggested I do the same thing to "get something done" - naturally I...ummm...I told her that milk was not recommended for anyone under the age of 1 (when what I really wanted to do was scream"OMG ARE YOU INSANE??" lol

). So neither my DP or any of his siblings ever were breastfed. Neither were his first two children; neither was his nephew - so, that's two generations of his family completely out!
I on the other hand was breastfed, along with my three living siblings (my mother also had my brother Finn, who was stillborn just like Josie). I slept on my mother's chest for a while too. Now, my DP is very supportive of AP, but the thing is, I sometimes think he doesn't know what he's supposed to "do" if he can't feed her. I think the other two children were kind of left to their own devices in baby devices rather a lot, so it's new for him to have this interactive, curious, REAL small person in the house that actually has an opinion about stuff!
So therefore I am attempting to teach him. He tend to kinda hold Bella like "one does" with a baby - you know, the hospital "hello hold" lol - baby in the crook of yer arm - you know. Bella usually prefers being near one's heart, upright. So he's getting used to that - and used to the fact that someone so small might actually have an opinion. I think he used to think crying was "what babies do" and not actually a means of communication - so he's just kind of getting used to the fact that he can pick Bella up and talk to her, and look in her eyes and that she then is interested and stops fussing. I think before, he assumed that either the baby was hungry, or that she simply kinda...felt like crying. Like she was a bit brainless, you know?
Actually though, Bella seems to be one of those very curious babies. I suppose she might be high needs sometimes, sure. Like when she wants to nurse constantly between the hours of nine and midnight or one in the morning...lol. Or when she doesn't want to be put down, but is obviously tired and will take a two hour nap ON someone or laying down with me, but not by herself in a nest, no matter how comfy I make it...ha!

I did think about it though: I was a VERY high needs baby - my gosh - I cried for hours and had a milk allergy and wanted to be carried up and down the stairs constantly...yes, I am surprised I myself wasn't thrown out of the window!

So in some ways - though about 100 times less seriously - she had my temperament, I suppose. I am still high needs, I guess, in terms of emotion. I like to talk, devote myself to my family and love, and expect the same in return or I get sad! It's true. But I GIVE as good as I get, that I know.
So I guess I try to always keep in mind that she is as smart as I am, and just learning, feeling insecure, very curious and hungry a lot! She has a tiny tummy, which needs filling frequently or it has hunger pain, which sucks. She has gas sometimes, which hurts, and now she poops, unlike in utero, which can feel weird I expect. Then sitting in poop probably sucks too, until she's changed. She wants to communicate but can't talk, which must be terribly frustrating for her - I'm sure it would be for me! She wants to see everything but can't focus on anything more than 15 inches away from her face, which must be annoying... She wants to be up and around, like we are - able to move freely, but she doesn't know ho to walk yet and being constantly on one's back and covered with blankets is enough to make her mad! Fair enough - all of it...
So I carry her about a lot in the sling, with her head popped out the top so she can see everything. She looks about alertly with her little eyes in her little head on top of a very strong neck already much more capable that it out to be of supporting her little melon!

I have conversations with her about how frustrating is must be to be a baby - long ones, and we talk about all sorts of things, looking into each other's eyes. I think pretending I understand her is very reassuring to her.
Then also, we tend to listen to a lot of different, interesting music. I walk about in time with the music, or rock her in time, or we dance, I sing, etc etc. She likes the blues and Philip Glass, Fleetwood Mac and Billy Joel; Paul Simon...all sorts. It's fun and we like it.

I mean, sure, I'm up at 1.30am sometimes feeding still, but now, it's come to the point where I literally can deeply doze or sleep on my side while she nurses - which has allowed me an extra - gosh sometimes three hours - of sleep a night that I was previously sitting up with her on the fake-boppy (I made my own), swapping from breast to breast. Now, I feed from the left boob during the night only! Then in the morning I swing her over to the other side and feed from my by then rather engorged right booby. I tuck a great big muslin cloth into my bra to absorb right-booby-milk in the night.
So she's attached, but we're working our way around.
Like you, I don't feel compelled to leave her with anyone - I don't know when I will, to be honest... The prospect of leaving her with someone else so I can have fun is...not fun to me! Wearing a sling has taken some practice but, we've got it fairly down-pat now for the most part.
I think the main part of me NOT going insane though, has been sorting the nights out, to be honest. Now that I get enough rest even WITH a suckling babe, days are only half as tiring! Hopefully DP will kinda get the hang of things here pretty soon - if only for his own confidence's sake! We shall see.
But hey, this has been a muse on the fact that I get what you're talking about, sister!
