middle of heel
The recommended site for heel punctures is the lateral (outside) or medial (inside) plantar surface of the heel. In small or premature infants, the heel bone (calcaneus) may be no more than 2.0 mm beneath the skin surface and no more than half this distance at the posterior curvature of the heel. Puncturing deeper than 2.0 mm on the plantar surface of the heel of small infants may, therefore, risk bone damage. When using incision devices, puncturing the heel at a 90' angle to the length of the foot is recommended.5 Such incisions create a 'gap' puncture (one which opens when pressure is applied) and further enhance blood flow. For infants, punctures must not be performed on: The posterior curvature of the heel. The central area of an infant's foot (area of the arch). Punctures to this area may result in injury to nerves, tendons, and cartilage. The fingers of a newborn or infant less than one year old. Earlobes.
Usually the heel.
Yes, infants can be punctured in the center of the heel, but it is generally avoided due to the presence of important structures, such as nerves and blood vessels. Heel sticks for blood tests are typically performed on the lateral or medial edges of the heel to minimize the risk of injury. Proper techniques and guidelines are followed to ensure the safety and comfort of the infant during such procedures.

Because of abundant capillary flow.
An afterpiece is a piece performed after a play, or the heel of a rudder.
A pulse check is performed on the brachial artery for an infant.

The most common site to draw blood from an infant is the heel, specifically the lateral or medial plantar surface. This area is preferred due to its rich blood supply and minimal risk of injury to the infant.
The depth of penetration is greater than the recommended 2.0mm for heel incision devices. Run the risk of nerve damage. In addition, 2.8mm lancet will not produce enough blood for the PKU, etc. testing requirements, Lastly, a puncture wound is typically of "lower quality sample" due to the puncture vs incision wound type.
The spelling is "Achilles' heel" (a potentially disastrous weakness or vulnerability).(The idiom comes from the legend of Achilles, impervious to harm because he was dipped in the river Styx as an infant. His only weak point was where he was held, by his heel.)
