Pregnancy markers fading

Now, 4 months after giving birth, I'm slowly sheding last vestiges of pregnancy.

-I've finally stopped peeing my pants when I sneeze.

-Last week my hair started falling out again. It was nice to have had long luscious hair, if only for 9 months of my life (or until the next pregnancy).

-My linea negra is almost completely faded

The only things that remain are:

- Still no period (yeay)

- Enlarged belly button -- will it ever shrink

- 15 lbs of pregnancy weight (+10 lbs of prepregancy I-got fat weight)

So I ask myself, when does the "I just had a baby" weight excuse become an "I'm just fat" fact.

When does the time frame "I just had a baby" become a distant past and one just starts looking silly blaming her fat(ter) self on the baby instead of chocolate and cookies.
