There is an error in the first sentence of the
“Questionnaires” subsection of the Results. The
correct sentence is: The BBQ Regularity item increased significantly over the months covered
by the study (
Table 4
).
There is an error in the first sentence of the fifth paragraph of the Discussion. The correct
sentence is: A steady CCR was established during the first year of life as well as a significant
increase in regularity (as described in the BBQ Regularity item) developed (
Table 4
).
