Brittany 16-month developmental red flags case guide
A two-page discussion post on the Brittany case: explain the developmental red flags against normal physical, social and cognitive milestones, how you differentiated normal from abnormal growth and development, and which screening tools, guidelines and management strategies you would use.

What does the milestone sequence actually show?
Work the case before you write anything, because the answer turns on comparing given data against milestone norms rather than on describing development in general. Brittany is sixteen months old, term-born with no intrapartum complications, and the history hands you a sequence: rolled front to back at six months, crawled at eight, pincer grasp at eleven, cruising at ten, and not yet walking independently. Set each of those against the expected window and the picture resolves quickly. Rolling and crawling arrived late, cruising is at the outer edge, and independent walking has not appeared at an age by which most children walk. That is not one isolated delay but a pattern across gross motor development, which is a different and more concerning finding than a single late milestone. Note too that fine motor development, represented here only by the pincer grasp, tells a less alarming story, so name the domain your concern actually lives in.
The other data are worth reading just as carefully, because part of the assessment is knowing what is normal. Birth weight of 8 pounds 1 ounce against a current weight of 26 pounds 9 ounces is a substantial gain that belongs in your growth assessment, and 24 ounces of whole milk daily is a volume worth commenting on, since excessive milk intake displaces iron-rich food and iron deficiency is itself associated with developmental delay — a link that turns two separate observations into one hypothesis. Socially and cognitively, mimicking adults, following one-step commands and settling when comforted are reassuring for the age, while a four-word vocabulary sits at the low end and deserves attention rather than alarm. Saying which findings are normal is what demonstrates the differentiation the prompt asks for, and it also stops the post reading as a list of everything that could be wrong with a toddler.
The management half should name real instruments rather than referring to screening generally. A general developmental screen and a validated parent-report tool are the obvious starting points; the case's language finding and the age both make an autism-specific screen appropriate at this visit under standard well-child guidance; and a haemoglobin given the milk history is a reasonable laboratory step. Say why each one, since the prompt asks for the reasoning and not the list. For management, the defensible line is referral for further evaluation rather than watchful waiting, because a pattern of gross motor delay at sixteen months warrants assessment, and early intervention services can be accessed while investigation continues. Note the grandmother's concern explicitly: a family member's worry about development is itself a documented predictor worth taking seriously, and the case placed it there deliberately rather than as background colour.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Compare each given milestone against its expected window rather than describing development generally.
- 02Recognise a pattern of delay across a domain as distinct from a single late milestone.
- 03Identify the normal findings, since differentiation requires naming both sides.
- 04Connect the milk volume to iron status and to developmental delay.
- 05Name specific screening instruments and justify each one.

Turn the brief into deliverables
- 01A two-page discussion post on the selected case.
- 02The developmental red flags, set against normal physical, social and cognitive stages.
- 03An explanation of how normal was differentiated from abnormal for this patient.
- 04Named standardized screening tools, clinical guidelines and management strategies, with reasons.
Which findings are reassuring, and which are not?
The motor picture
Set rolling at six months, crawling at eight, cruising at ten and absent independent walking at sixteen months against expected windows, and name the pattern.
Growth and nutrition
Assess the birth-to-current weight change and the 24 ounces of whole milk daily, linking milk volume to iron intake and iron status to developmental delay.
Social and cognitive findings
Identify mimicking, one-step commands and comfortability as reassuring, and place the four-word vocabulary at the low end for age.
Screening and management
Name a general developmental screen, an autism-specific screen appropriate to the age, and a haemoglobin, each with a reason; then argue for referral and early intervention.
Where are the milestone norms?

Search sequence
- 1.Write out every milestone in the case with its expected window before drafting.
- 2.Check the well-child schedule for which screens are indicated at this age.
- 3.Read on iron deficiency and excessive milk intake in toddlers to support the nutrition link.
- 4.Decide the management position — referral versus monitoring — and find the basis for it.

Review before submission
Common mistakes
- Describing infant and toddler development generally without working the case data.
- Naming the walking delay and stopping, missing the pattern across gross motor milestones.
- Listing only the abnormal findings, so nothing is actually differentiated.
- Overlooking the 24 ounces of whole milk and its link to iron status.
- Referring to developmental screening without naming an instrument.
- Recommending watchful waiting for a pattern of delay at sixteen months.
Submission checklist
- Every given milestone compared to its expected window.
- Gross motor delay described as a pattern.
- Reassuring social and cognitive findings named explicitly.
- Milk intake, weight and nutrition addressed together.
- At least two named screening instruments, each justified.
- Referral and early intervention addressed rather than watchful waiting.
