When do you consider a baby bump a real bump? When you can't suck it in anymore and it's not soft like bloat is? Mines never really been soft and squishy, whatever bump I've seen has been firmer and it doesn't disappear if I suck in. 2nd baby I know you show earlier with so I was just curious. Also can no longer squeeze into buttoning my pants at all.
