Please address how to deal with flared ribs.

This condition mostly arises from poor development, primarily caused by malnutrition and calcium deficiency, so it's important to supplement calcium for the baby promptly. While supplementing calcium, it's best to also provide vitamin D, which promotes calcium absorption. Generally, doctors recommend cod liver oil or AD capsules. Getting more sun exposure also helps with calcium absorption. Long-term incorrect sleeping posture can also lead to rib flaring, so parents should correct this promptly.
