Not necessarily. Daycare aged children catch 6 to 8 viruses a year. They are much more likely to have contracted a recent respiratory virus than an adult. They most likely have higher antibody levels to Coronaviruses than their parents or grandparents, although I don't think much is known about T-cell immunity longevity with these viruses. 

The low risk of COVID-19 infection extends to birth.  But you are right that if ADE from non-COVID coronaviruses were an issue, you might expect it to be problematic for toddlers and school age kids who have a fair bit of recent exposure no non-COVID-19 coronaviridae.
