The OB-GYN-recommended seatbelt adjuster that locks your lap belt low and safe — below the bump, onto your hips — on every single drive. Installs in 2 minutes.
Shop Mama Bub — $39.99Your lap belt is sitting in the one place doctors warn against.
From around 16 weeks, the belt starts riding up over your belly — and in a sudden stop it presses exactly where it shouldn’t. The injury mechanism isn’t speed or impact force. It’s the belt’s position — which means you can’t drive carefully enough to fix it. A wrongly positioned lap belt can raise placental abruption risk by up to 70%, regardless of how slowly you’re going.
Your hip bones are built to absorb crash force. Your baby is not. That’s why OB-GYNs say the lap belt belongs low — below the bump, across the hips.
