Re. JB’s comment about a noisy toddler. A toddler might be prolific IF he or she is creating. My children were sometimes noisy toddlers. When they were creating out of their own little innovations and imaginations by reproducing what they saw in the world, making something out of the box instead of the toy they’d received, or interpreting what they heard, saw or read, they were being prolific and have left a mark that is indelibly written on the people whose lives they’ve touched!
