In the post, Sinclair says:

“So today I took my four-month-old son to the pool. While putting Christian's pool hat on, a woman (maybe mid 50s) comes up and makes conversation with me about Christian, asking me his age, how much he weighs, how he sleeps, etc.

“She then proceeded to tell me that the men at the pool would feel more comfortable if I was in a one-piece swim suit because a bikini isn't appropriate for a mother, especially one who's 'still recovering.”

Presumably, the woman was referring to Sinclair’s post-partum stomach, with (shock horror) visible stretch marks.

The post continues:

“Anyone who knows me knows I had a few words for this crazy, ballsy woman. But instead I just smiled, kissed my son and told her: 'I'm proud of my body. In just one year I've gained 50 pounds, and lost 37.

“I've grown a human and given birth to a beautiful miracle. My body provided food for my child. So, no, my body might not be the best sight for other men to see.”
