Don’t baby proof your home
Nowadays, everyone advises you to baby proof your home when the baby starts crawling but there was a time, in the 1950s, in where baby proofing your home was seen as a sign of “lazy parenting”.
If your baby still doesn’t crawl, he might be getting his workout by crying. What? Yes, in the “Dos and don’ts of parenting babies” from the 50s, it said that a “lusty cry” could be an excellent exercise.
