Hrt has worked so beautifully for me and I am so very happy. I do have some concerns about some things, they aren't bad things at all but just curious.
There were some questions I couldn't  seem to find in Google either.
So I have pretty wide feet and for some reason this bothers me more than having no vagina ( How do most people who have wide feet get over this.

All of the girls in both side of my family have humongous thighs and very small breast.. How likely am I to inherit those attributes.... I don't mind having small breast since I find them cute but I really hope my thighs don't get that huge... Just wondering how it usually works.

Is it normal to feel like a little girl on daily basis.. My mom is laughing saying I'm behaving very girly like, is this normal?

Last question is, does it hurt when the duct of the breast starts to form?? My breast are starting to form but still have male nipples, so I'm curious if I am going to to be in pain when it gets to that stage :< since they really don't hurt much unless you squeeze them hard.

i am not really sure on your specific question, but acting overly girly and feeling like a little girl I would say are totally normal from what I hear most new trans women go a bit overboard at first, decades of being forced to hide every bit of that part of yourself, when finally let loose, it can be like holding your breath for a long time, when you finally breath again its in gasps and shuddering desperate gulps of air. I personally am trying hard to limit myself, not go into that barbie stage where everything is pink and ultra fem, I am almost sure that isen't who I am so I am trying to be a bit more casual. (it hasen't worked all that much, mostly I just worry I am acting too overly fem or not fem enough then I start to freak out.)

so I say dont worry about how your acting now, you missed a childhood as your true self, your owed at least a few days dressing up as a princess fairy and skipping through a open field. :-)

Hi - I'm glad you're happy with developments so far! As to your concerns/questions...

wide feet: depending on what is making them wide, muscle or fat, they may narrow out a little bit. If it is basically because of your bones then unfortunately you're out of luck.

humongous thighs and very small breast: you're probably going to inherit some aspects of this, but not necessarily.

feeling like a little girl: well, that's your mother's observation but is it how you feel? HRT can indeed have some effects on mood and, as a result, behaviour.

does it hurt when the duct of the breast starts to form: it can. Often it does and sometimes it doesn't. Either way breast will develop. I would not recommend squeezing them unless your intention is to milk yourself!
