1. Mayo Clinic Research
Date: 2017
Because this is the most recent study, it comes in at number one on our list. This Mayo Clinic study reported that an age gap of less than 6 months resulted in a higher risk of premature birth, as well as a number of mental disabilities, and less than two years of a gap increased the risk of autism. They suggest parents wait at least two years before having kids, for a lower risk of birth defects and health issues.
Now that you know the science behind age gaps in siblings, we hope you enjoyed learning from this list of easiest age gap between babies: 5 research studies.
