Baby Head Fixing (Fixed Head):* **Definition**: Once the head is engaged, if it becomes *firmly lodged and doesn’t move up when pressed**, it's called **“head fixing.”* 🔐 *Fixing = Engagement + Stability* A *fixed head* means it is *locked into the pelvis* and **less likely to float back up**. This is usually a *good sign* that the pelvis is adequate and the baby is getting ready for delivery.

If the *head is floating* (not engaged), especially in first pregnancies near term, it may signal *malpresentation or a mismatch* in size between head and pelvis (CPD).
