Not at all! Lol that made sense :)
I'd say gradually! I think the first time it actually got hard was because I was experiencing Braxton hicks lol! Even now my stomach is still pretty soft at times, I think it just hardens when he gets closer to my skin if that makes sense? Lol he's constantly in my ribs so my lower belly is usually soft. Hope that doesn't confuse you ahahah!!
Same here lol nobody believes I am almost 27 weeks! Did it get completely hard or was gradual?
My tummy didn't start getting hard till around 28 29 weeks I'm 32 weeks and people still don't believe I'm this far along. Lol
