Getting your kid to bed at night is seriously one of the most challenging things you'll ever have to do. Most

kids are just so full of energy that they'll tire you out before they're halfway through their store of energy. An easy

thing to calm down your child to get into bed is giving in and allowing some iPad screen time. However, it's really

not a great idea, just like you thought.

Researchers at theArizonaStateUniversityconducted a study with 547 kids between the ages of 7 to 9. Their

parents tracked how much screen time the kids were allowed along with their sleep patterns. The study found

that kids who did not engage in screen time before bed slept for 23 more minutes every week and also went to

sleep about 34 minutes earlier than those playing with iPad. Although that might not seem like so much more

time, quality of sleep is vastly important in Children's development.

The CDC's (美国疾病控制中心)2018 National Youth Risk Survey outlines that good quality sleep can impact a

child's life in many ways, including affecting grades and also weight gain. Students with an "A" average slept for 30

or more minutes per night than those with a "D" or"F" average.

A 2018PennsylvaniaStateUniversitystudy showed that children with irregular bedtimes had a higher risk of

having increased body weight. Those with consistent and age-appropriate bedtimes when they were 9 years old

had a healthier BMI (体质指数)at age 15 than those with irregular bedtimes.

Hard as it is, it's really important not to give in and hand over an iPad to your child who is about to go to bed.

Just like it's important for adults to go to sleep without any distractions, it's even more important for kids.

The COVID-19 vaccination（接种疫苗）rate in the US has fallen to newlows in recent weeks, threatening

President Joe Biden’s goal of having 70 percent of American adults with at least one shot by July 4.

With just less than one month from July 4, the current vaccination rate will put the US at somewhere

between 67 percent and 68 percent of the adult population with at least one dose（剂量）by Independence Day. To

reach 70 percent by July 4, around 1.6 percent of the population needs to get their first dose per week from now

until July 4.

The Centers for Disease Control and Prevention（CDC）reported last week that 63 percent of adults

hadreceived their first dose of a COVID-19 vaccine. That was up slightly from 62 percent from the report a week

before. The additional 1 percent of adults completing their first dose is the lowest since the CDC started tracking

the vaccination rate in mid-February.

On average, fewer than 1 million shots are given out per day, a decline of more than two-thirds from the peak

of 3.4 million in April, The Washington Post reported. In South Carolina, about 71,000 residents got a shot in the

week leading up to June 3, compared to a high of nearly 300,000 in one week in early April, according to data from

the CDC.

The slowdown is moreprominentacross the South and Midwest. Twelve states have seen vaccinations fall to

15 daily shots per 10,000 residents. Less than a quarter of black Americans had received their first COVID-19 shot

as of June 7.

James Hildreth, CEO of Meharry Medical College, told Politico, “We need to make a stronger effort to bring

the vaccine to the communities, rather than relying on the communities to come to vaccination centers.”

The sharp decline in vaccination began in mid-April when federal officials temporarily stopped the use of the

Johnson＆Johnson vaccine while they investigated rare blood-clotting（凝血）reactions.

The “low-hanging fruit—thosepeople who ly want to get vaccinated without you telling them anything” have

already been vaccinated, which has led to the slowdown, Dr Anthony Fauci, director of the National Institute of

Allergy and Infectious Diseases, said on a White House-organized call with community leaders last week, according
