Do babies have iq scores?

Babies are so smart compared to their age. Do babies have IQ scores? I know that IQ scores are based on age, so is it fair to say that we are all born at a perfect IQ score and we either move up or down?

I don't know for sure, but I imagine if it's possible to test the baby a score could be attained (see last paragraph)

I.Q. INFO:
Ranking of IQ scores was developed by Lewis Terman in 1916 as a way of categorizing intelligence levels. The ranking of typical ranges of IQ scores and what they mean are summarized below:

Over 140 - Genius or near genius
120 - 140 - Very superior intelligence
110 - 119 - Superior intelligence
90 - 109 - Normal or average intelligence
80 - 89 - Dullness
70 - 79 - Borderline deficiency
Under 70 - Definite feeble-mindedness

The distribution of IQ scores in the world falls along a normal distribution curve, and can be summarized as:

50% of IQ scores fall between 90 and 110
70% of IQ scores fall between 85 and 115
95% of IQ scores fall between 70 and 130
99.5% of IQ scores fall between 60 and 140

Roughly 5% of the population has IQ scores under 70; this is considered the benchmark for mental retardation. On the other end of the scale, only 1% of the population falls in the 135 and above category, which is the benchmark for genius.

What is the relevance of these scores? At best, they measure academic intelligence or the ability to succeed in an academic environment. Many other kinds of intelligence have been discovered and categorized that are not measured by these tests, such as the physical intelligence demonstrated by athletes, and musical/artistic genius. A rough ranking of what each IQ score means occupationally is shown below:

140
Top Civil Servants; Professors and Research Scientists.
130
Physicians and Surgeons; Lawyers; Engineers (Civil and Mechanical)
120
School Teachers; Pharmacists; Accountants; Nurses; Stenographers; Managers.
110
Foremen; Clerks; Telephone Operators; Salesmen; Policemen; Electricians.
100+
Machine Operators; Shopkeepers; Butchers; Welders; Sheet Metal Workers.
100-
Warehousemen; Carpenters; Cooks and Bakers; Small Farmers; Truck and Van Drivers.
90
Laborers; Gardeners; Upholsterers; Farmhands; Miners; Factory Packers and Sorters.

There is also considerable evidence that IQ scores can be improved by changes in ones environment, particularly for children. Children who have been read to more often or have been subjected to variety in their environment tend to improve their scores over time.

To clarify, there's no such thing as a "perfect IQ score". It's actually been said your IQ never changes because it's more of a measure of potential than actual intelligence-- which is why someone with less experience and teaching can still, logically, be smarter than someone way older.
