Lactose intolerance is a carbohydrate breaking down insufficiency and is very rare in children
Cows milk protein intolerance is inability to break down a protein and is not uncommon

2nd line investigations for developmental delay?

Audiology, ophthalmology (Electroretinogram, VEPs)
82
When does swimming reflex disappear?
6-7 months
83
What are the 3 types of cerebral palsy? Subdivisions of each?
Spastic - hemiplegia, quadriplegia, diplegia/paraplegia

Ataxic/hypotonic
84
Discuss the use of growth charts for preterm kids?
From 32-36+6 gestation use left hand side of normal chart, plot up to EDD+2 weeks. Thereafter from 0-1 use gestationally corrected age on normal chart
For under 32 weekers used low birthweight chart
85
What age do you plot on growth chart for babies born under 37 weeks? How long for?
Gestationally corrected age (so plot the baby's calendar age minus how early they were by an arrow)

For 2 years if less than 32 weeks
86
How might newborn babies weight change and why? What is abnormal?
After first few days may lose 5-10% of body weight (more than 10% abnormal) due to fluid loss
Should start putting back on at 5d and be BW+ by 10-14days
