How parents spend time with their kids

For Quartz, Dan Kopf and Jenny Anderson on how time spent with kids changes with age:

In the very beginning, it’s all about physical care, otherwise known as the stuff that makes your arms tired. A fifth of time parents spend with kids before their first birthday is on what could be described as keep-them-alive tasks. At age 1, this falls dramatically and it becomes playtime: peek-a-boo, stack the box, dinging and singing, making art, dancing, hide and seek, jumping in puddles. The share of time spent playing with children peaks around age 1, and then is then slowly replaced by a variety of other activities, including socializing and watching TV. Overall, time spent with children declines as kids get older.

Sounds about right. Although it makes me a bit nervous for the future.
