Sorry didn't respond re soft/hard bumps before!
So not like super soft, but mine goes back and forth over the course of the day still. When I wake in the AM and I haven't eaten or drunk in the past 8+ hours, it is softer. When I sit, like right now, it is really soft. It doesn't usually get really stretched hard feeling until bedtime, after eating and drinking all day. Sometimes during a growth spurt, it gets hard and tight, but not normally. I just don't have a tight stomach. Like around 16 weeks, it was tight all the time. By 18 weeks, it felt noticeably softer, because my body had adjusted to the growth spurt.
Like I said, it's pretty soft right now as I'm sitting, but baby is kicking away in there. It is just normally not super firm, I think I have a layer of fat around mine or something though!
