Yeah, this is definitely something that requires patience. From what I've read, most of the time fat redistribution and muscle changes usually don't really start until months 6-8, and it takes years for them to really start getting into official feminine ranges.
I admittedly have a hard time with this myself. Sometimes because it's going so slowly I start getting down on myself because it feels impossible. So I'm in the same boat, and I've been on HRT for just under two months. But again, it takes time.
Think about how long your original puberty took. With me, it started when I was about 13, but my voice didn't really finish changing, and the body hair didn't really finish growing in, and I didn't really start getting significant "adult" muscles until I was at least 15. And even since then, I've still been changing in subtle ways over the years. HRT, and your second female puberty, is going to go pretty much the same way. There are some things that are almost immediate once the hormones come in, mainly your emotions going haywire and your sex drive changing, but for the rest of it, it's going to be like another puberty all over again. Changes will really start becoming noticeable after a year or so, will be about 90% complete by 3 years or so, and then there's still some subtle feminization that will take place even after that, which is ongoing and progressive and never really stops.
This is not something that can be rushed. It's impossible to make it go faster. And I know it's hard to wait. I HATE this too, as I myself want boobs and a butt yesterday, but there's nothing we can do to speed it up. We can just enjoy our newfound selves, enjoy the changes as they come, and continue to live life in the meantime. And then one day in the mirror, voila! You'll look back and you'll hardly recognize yourself.
Taking pictures or making videos every month or so is a big help. Even at this early stage, when I still have barely feminized at all, I'm still looking back at the pre-hormone videos that I made just two months ago, and serious saying "Wow, that was me? How the hell did I put up with that old body for so long?" Just, again, don't obsess over it so much. Relax. Let it happen, try to be happy in the meantime, and check your progress every month or so when you need an emotional pick-me-up. You'll be amazed every time you look back. It's all about focusing on what HAS changed, and being happy for that, rather than focusing on what hasn't changed yet, which only leads to feeling depressed and inadequate.
