What to do while babysitting a 4 year old boy

Hi everyone!

So, my mom lined up a babysitting job for me today for sometime this week, and I need some advice.
Usually I babysit kids in like 2nd through 5th grade (mostly 3rd and 4th graders).
When I asked my mom how old the kid was, she said 4 years old. I'm pretty good with kids, but I've never babysat someone that young. I'm scared I'm not going to know what to do with him and what to talk about or like what games to play. I really dont want it to be awkward.
I dont really know what 4 year old boys are into.

Any advice on how to have fun with this kid for a few hours?
Also, is there anything extra I should know and be prepared for before babysitting him?
Thanks a bunch!!

The other day I babysat a 5 year old, 3year old, and a one year old all boys, so I know a thing or two.
Use high fives as a reward instead of candy or something
he'll probably be into things like building and cars. hot wheels might be a hit. ask the parents what he likes to do too, they might not let him play with certian things.

watch em like a hawk and do not keep your eyes off him the terrible 2s last 2 years.say that cause I fell down the stairs playing on them when I was 4 while I was being baby sat cause they were watching tv talking to their boyfriend on the phone

4 year olds are tough. I do have a small piece of advice to give tho, never do "one" activity for too long. Includes some coloring or finger painting. Also the cars and building things are a good idea too, try balloons and balls too.Television/Movies are a no-no unless it's time to relax and settle down and the parents are like 10-15 mins away.

I babysit all ages from about 4monthsish- 8 at the moment

4years olds arent terrible but most all ways have that one word that sometimes does your head in ' why ' evertytime lol

anyway.. like kelseymichelle said giving them high fives is a good iunstead of candy.
playing with cars, colouring, painting, building, if your going out that day to the park or something a football would be good, or if he has a bike, scooter that kind of stuff, if you've got to feed him like lunch or something make sure you dont give him a lot of chocolate,sweet,crisps becuase he will become energetic for a while and hyperactive.

also like lucky025 sais dont forget, not to play the game for too long as they will start to moan and get bored.

hope I helped, goodluck
