Vitamin D deficiency in children may present with rickets, night terrors, and other symptoms. Early signs of vitamin D deficiency include irritability, fussiness, excessive sweating irritating the scalp, head shaking, and night terrors. During the active phase, main manifestations involve skeletal changes and delayed motor development, such as a square-shaped head, rib beading, Harrison's groove, and pigeon chest. It is recommended to supplement vitamin D as soon as possible.
