why are dad bods more socially accepted than mom bods, & she’s the one that has given birth?🥴

Because when you become a mum you lose sight of who you were and there's so much pressure from us ourselves to get back to a mindset before we were parents. Easiest way to do it is through looks.
I look better now. I like how my body changed. Yes, I need to lose weight, but for health nothing else.
