Formula feeding and complementary feeding — structured clinical encounter

Station brief (candidate)

You are the paediatric registrar in a general clinic. A six-month-old is brought for review. The family has begun adding rice cereal to the bottle, has switched to whole cow's milk as the main drink because the infant "seemed hungry", and has started giving honey in water for "wind". You have 10 minutes to take a focused feeding history, correct the unsafe practices, and counsel on the safe and timely introduction of complementary foods. [1]

Information available on request

• Six months old, born at term and previously growing along the 50th centile; the family has added rice cereal to the bottle for two weeks and switched to whole cow's milk as the main drink one week ago. [1]
• The infant has good head control, sits with support, watches the family eat and reaches for food; the tongue-thrust reflex has faded. [2]
• Honey has been given in water on several days over the past month for "wind". [1]
• Examination: alert, no pallor, normal tone and reflexes; weight and length on the 50th centile; no eczema. [1]

Tasks

1. Take a focused feeding history that elicits exactly what the infant receives and how each feed is prepared. [1]
2. Identify and explain the three unsafe practices and correct them. [1]
3. Counsel on the complementary feeding ladder: iron-rich first foods, early common allergens, and texture progression to family foods by twelve months. [5]
4. Summarise the safe formula feeding plan, including preparation, volume guidance and responsive feeding. [7]

Model approach

• Feeding history: establish the formula brand and stage, the exact preparation (number of scoops and volume of water), the total daily volume, the frequency of feeds, and any solids, drinks or additions already introduced; plot the weight, length and head circumference to check for centile crossing, and confirm the developmental signs of feeding readiness. [1]
• Correcting unsafe practices: stop adding cereal to the bottle (it distorts intake and risks choking; instead begin appropriate complementary foods at around six months); stop whole cow's milk as the main drink before twelve months (iron deficiency anaemia and renal solute load — return a first infant formula or continue breastfeeding, with cow's milk as the main drink only after twelve months); stop honey in any form (Clostridium botulinum spores can germinate in the immature gut and cause infant botulism). [1][10]
• Complementary feeding ladder: begin iron-rich first foods — pureed red meat, lentils, beans or iron-fortified cereal — since iron stores are depleted by six months; introduce common allergens such as egg and peanut early and keep them regularly in the diet, because early regular exposure induces tolerance; progress texture quickly from puree to mashed, lumpy and soft finger foods so the infant is managing family foods by twelve months. [1][5]
• Safe formula feeding summary: a first infant formula (stage 1) remains appropriate right through the first year; prepare each feed by boiling fresh water, cooling it to no less than 70 degrees Celsius, adding the exact number of level scoops, and using or refrigerating immediately; guide the total daily volume by appetite and growth rather than a fixed amount, with a working early figure of about 150 mL per kg per day. [7]
• Safety-net: the family returns for review of growth and feeding, and a clear safety-net is given — any infant who becomes pale, lethargic, dehydrated or unwell, or who develops a reaction to a new food, returns promptly. [1][10]
