When it comes to vaccinations, but what do parents need to know before they take their children to the doctor? For children younger than 10, getting fully vaccinated for flu season may mean getting four shots this year.
How much do children know about the flu? And are they prepared for all those shots?
ABC News' senior health and medical editor, Dr. Richard Besser, sat down with a group of children between the ages of 6 and 8 to talk about getting shots.
Grace Sadim, 7, knows that you go to the doctor "to get the flu shot."
And William Keenan, 8, knows all about the flu: "The white blood cells, they go around and they get to know what weapons they need," he said, but his younger sister doesn't understand.
"She thinks she gets shots to hurt her," William said.
Ryan Zucker, 6, hates going to the doctor for the same reason. "I hate checkups," he said. "Because of the finger prick thing. Really hurts."
When asked if they know why they get shots, Ryan said "to not get the worst disease, diphtheria. ... Diphtheria is a really bad disease. Even more bad than the swine flu."
As young as they are, the children had already developed their own methods for coping with shots.
"I close my eyes ? I close them really tight," said Yamila Frej, 7. "And, then, it doesn't hurt."
It helps when the doctor tells her what's going to happen, "so it just doesn't come out of nowhere and I'm not ready," she said.
All the children agreed that it would help to think about something nice when getting a shot, so it doesn't hurt so much.
"I think about my birthday," William said.
"A dog named Zeke, who eats everything," Grace said.
For Yamila, her happy thought is "my No. 1 dream, which is to go to Paris and turn into a millionaire."
Grace's sister, Sophia Sadim, 8, said it would help if parents "explain why you get it and, if you don't get it, what can happen to you."
Yamila said, "Sometimes they [parents] hug you and they encourage you and they say it's all right. It's just going to be for one second and, then, it's not going to hurt anymore."
"I just want them to do it," Grace said. "Get it over with."
Besser shared his advice with "GMA" on how to get your children through their shots as painlessly as possible. "These kids had so much that they could teach us," he said.
It's important for parents and children to understand why they may be receiving four shots this flu season, he said.
Children will receive two H1N1 shots, three weeks apart. And kids younger than 10, who are getting the regular flu vaccination for the first time, would need two doses.
"If you're under 10 and you've never had a flu shot before, you'll get two for seasonal, two for swine." he said.
"Explaining that to children will help a little," he said.
Besser also acknowledged that parents are concerned about the number of shots. "If we can get parents to understand why, that's the first step," he said.
When it comes to taking your child to the doctor, Besser said, the work you do to prepare them really makes a difference.
"Be age appropriate," he said. "Let them know what's going to happen before it happens."
For toddlers and older children, don't talk to them about it too far in advance. That just gives them more time to worry about it. But let them know what will happen when they get to the doctor, Besser said.
Let children decide which arm and where to sit
