A study comparing infant care revealed that the amount of stimulation babies receive affects their sleep. At six months of age, the babies in the study with a less stimulating daytime routine slept an average of two hours more per day than those with a more stimulating routine. Since sleep plays a very important role in a child’s development, parents would be wise to reduce the amount of stimulation their babies receive.

Summarize Argument
The author concludes that parents should reduce the amount of stimulation that their babies receive. The author references a study in which babies with a less stimulating daytime routine slept an average of two hours more each day compared to babies with a more stimulating daytime routine. To connect this study to the conclusion, the author claims that sleep is very important for children’s development.

Notable Assumptions
The author assumes that sleeping more is better for babies––what if there is a point at which too much sleep becomes detrimental? Also, the author assumes that the studies were conducted in a way that allows their results to be applied to babies in general. The author also assumes that sleep would be better for babies than the stimulation that is being sacrificed in order to enhance their sleep.

A
Babies’ muscular coordination is unaffected by the amount of stimulation they receive.
The argument connects stimulation to sleep, and assumes that more sleep is better for babies. Muscular coordination being unaffected by stimulation is unrelated to the argument.
B
Babies with less stimulating routines usually get extra sleep during the day.
Whether the sleep occurred during the day or at night is not relevant to the argument; the argument only discusses average sleep time.
C
Studies showed no correlation between stimulation and amount of sleep for children three years of age or older.
The argument is about infants and discusses a study on six month old babies. Facts about children three years old and older is not relevant to the argument.
D
The babies who had a less stimulating routine gained weight at an average rate.
We don’t know anything about the weight gain of babies with a more stimulating routine. (D) just gives a separate fact about an unrelated factor for one of the two groups of babies, so this does not weaken the judgement made in the argument.
E
The stimulation that babies receive helps them to develop intellectually.
(E) introduces an aspect of net effect. (E) shows that babies with a less stimulating daytime routine may be missing out on intellectual development. This weakens the argument because it provides a reason that a more stimulating daytime routine may be beneficial.
