Cue Based Care:What is it?
To follow the principles of Developmental Care it is important to grasp an understanding of what state a baby is in and the optimal times to interact with them, which leads to a need to understand their behaviour cues. These are their way of communicating.
![Page 9: Late preterm and dev care 2009](https://reader033.vdocument.in/reader033/viewer/2022051617/559c89651a28ab3e7f8b4588/html5/thumbnails/9.jpg)
Cue Based Care:How do we understand Behaviour Cues?
Behaviour cues are...
the signs and signals given to us by babies
They are their way of communicating... when they are calm, ...when they need time out and ...when they are ready to interact.

Understanding Behaviour Cues Summarised:
• A calm baby will show signs such as:- puts hand to mouth- curls up- will grasp & hold a finger or toy- will bring hands together- will softly close eyes

Understanding Behaviour Cues Summarised:
• A baby that needs time out shows: Motor signs - splays fingers
- has a stiff arching posture- is flailing and disorganised- the sitting on air sign (arms
& legs in air)Autonomic sign - YawningAttention / Interaction signs
- turns away / looks away- Hyper alert (staring wide eyed)
Other Signs - crying- fluctuating heart rate- oxygen desaturation- colour changes- closes eyes

Understanding Behaviour Cues Summarised:
• A baby is ready to engage when it:- is smiling- has a relaxed posture and face- is cooing / babbling- is making eye contact

SIDS the prevention campaign:1) put baby on back to sleep from birth 2) sleep baby with face uncovered3) cigarette smoke is bad for baby4) safe sleeping environment for baby, night &
day: safe cot, safe mattress, safe bedding
Why?Since the SIDS and Kids Safe Sleeping Campaigns began in the early 1990's...
>4,000 Australian babies savedreduced the rate of SIDS by 84%.

Infant Positioning

![Page 18: Late preterm and dev care 2009](https://reader033.vdocument.in/reader033/viewer/2022051617/559c89651a28ab3e7f8b4588/html5/thumbnails/18.jpg)
Infant Positioning when awake:• Prone (“tummy time”):
– Clean, flat surface (pad on floor) – No sharp angles (furniture) nearby– Pillows NOT recommended
• Side Lying:– put a pillow at the baby’s back only
to support position to encourage hands in view
• Supine (back):– Create a nest using a rolled blanket
and ensure it remains close to the baby’s body and under legs
![Page 19: Late preterm and dev care 2009](https://reader033.vdocument.in/reader033/viewer/2022051617/559c89651a28ab3e7f8b4588/html5/thumbnails/19.jpg)
Key points... • Supervision of infant is MANDATORY
• Flexed and curled up positions are encouraged as these reflect the environment of the womb
• Ensure:- shoulders forward
- hands towards midline in supine & side lying
- hips and knees tucked
- alternate positioning of head side-to-side when asleep (supine)

LPI’s are special!
• Essentially a preterm infant in a term infant’s body↓↓↓
• Poor immunity• Poor feeding • Parents unprepared, stressed• Delayed discharge home or...
difficulty with normal care at home

IMPLICATIONS FOR PRACTICE
• Midwives• Neonatal Nurses• Parents• Multidisciplinary Team• GP Practice/ Community Health agencies• Follow Up? (Service provision is poor)• Early Intervention Services?

The Late Preterm Infant
• POOR OUTCOMES
• MISS OUT ON SERVICES
• PROBLEMS AT SCHOOL AGE
• FUTURE DIRECTION OF RESOURCE ALLOCATION AND FUNDING ?
