[2025-10-02T00:05:11.618378] [PI reasoning] **Analyzing developmental milestones**

I need to find out which milestone, if absent in a 3-year-old child, indicates delayed development. The options are hopping on one leg, drawing a square, feeding with a spoon, and catching a ball reliably. I'll consider what is expected by age 3. In terms of gross motor milestones: at 3 years old, kids can climb stairs with alternating feet and stand on one foot for a few seconds. It seems that hopping on one foot is typically achieved at age 4.

I'm trying to access normative milestone ages, but it’s tricky without a specific question. I could reference standard guidelines like "CDC developmental milestones." However, based on what I know, by age 3, kids can stand on one foot briefly, climb stairs, ride a tricycle, and say three-word sentences. They can copy a circle and feed themselves well. The only milestone expected by this age is feeding with a spoon. For citations, I could look into established normative charts or PubMed articles.

[2025-10-02T00:06:03.906875] [PI reasoning] **Evaluating developmental milestones**

It's not straightforward, but I can rely on standard developmental milestones. For instance, Parker's 1993 study suggests that children 3-4 years old can perform one-footed hopping, with a normative milestone around 4.4 years. However, the article mentions that the ability to "hop on one foot at least twice" is a sensitive indicator for children aged 24-36 months. This implies that while some children can do it by two or three years, the milestone likely emerges around three years. Let's verify this!
