There are so many stories about how so-and-so famous person "got her body back" after her baby was born. "Doesn't she look great? Way to go, girl!" The flip side of all that seemingly innocuous congratulatory fussing is the underlying assumption that postpartum bodies are only valuable if they look like never-had-a-baby bodies. There's enough outright criticisms, too. Honestly, why even go there when there are so many things you can do instead of critique a mom on her postpartum body?
To be sure, there is nothing wrong with a postpartum person wanting to work out and eat well. There's also nothing wrong if the new mom doesn't want to (or can't) work out and eat well. The glorification of the "we can't even tell you were pregnant" body feeds into our culture's obsession with shaming moms who don't immediately (or ever) look like they did before they were pregnant. What is so bad about looking like you had a baby? Why is this something we need to cover up? I'm no medical doctor but, if I'm honest, I always question how healthy these immediately-back-to-pre-baby bodies are. However, and again because it's worth repeating, that's me being snarky and isn't necessarily helpful or productive.
