A clinic nurse is assessing infants and toddlers for fine and gross motor development. Which child should the nurse refer to a healthcare provider for further evaluation?

A. 3-year-old walking on tiptoes: While some children may walk on their tiptoes occasionally, it's not necessarily a cause for concern unless it's persistent or accompanied by other developmental delays.B. 1.5-year-old attempting to scribble: This is a typical stage for exploring hand and finger movements, leading to early attempts at drawing.C. 5-month-old with whole hand grasp: At this age, infants use their whole hand to grasp objects, which is a normal developmental step before developing a more refined pincer grasp.D. 3.5-month-old with diminished Moro reflex. The Moro reflex is a normal reflex in newborns that typically disappears by around 4 to 6 months of age. A diminished or absent Moro reflex before this age could indicate neurological concerns or developmental delays. Referral to a healthcare provider is necessary for further evaluation.
