Feeling like a bad mom already

Baby Mama to #3 • 👼🏻💙1/17/18 🌈👶🏼💖12/30/18 👶🏼💖 9/28/20

Anyone not able to distinguish between arms and legs and where there baby is positioned? I am almost 30 weeks with my first and feel like everyone else knows there bodies/babies and where all their body parts are located😩😩😩 I know it’s super trivial, but it’s making me sad I couldn’t tell you if babies head is down/up/in my rib cage/etc.
