Natural Reinforcer List
Give "go play" and pull child back to you by back of shirt. Do several times. It usually builds a smile and a lot of times when you don't grab the shirt the child will back up to you to do so.
"I'm gonna eat your toes!" Take child's foot toward your mouth with pretend chomping sounds. Doesn't seem to make a difference if the child has receptive language or not, just the anticipation after the first or second time of trying to pull away with laughter, the child usually gives you the other foot.
Say "do this" and make roar sound. When child does, act terrified and fall off chair. May take a few "do this" but most kids love the idea of making you react.
Instructor puts head into child’s stomach, tickly burrowing of head, real laughter zone.
Wind up your hand like it is a toy until your wrist hurts (almost), use cranking sound effects, then let it go and flap your hand wildly over the table and child in flip flop motion.
Fall asleep and snore loudly on child's lap then wake up suddenly for the school bell -- ding ding ding.
Do emotions like -- mad [ggrrrrrr], sad [real sappy boo hoo hoo and drip water on face for tears (all very fake)], happy [with the happy song and dance]. Sad has been number one requested for the last three years, I guess I got the drama right.
Say give me five or high five but lose your hand in your sleeve, have child help you find, then lose other hand, etc.
Position water bottle above child's head, tilt ever so slightly in anticipatory way, drop droplet. Most kids dig this big time. Fair play however is allowing them to get you and they are usually less reserved about the amount they drop!
Lean over until child leans on your back then pick him up, hanging behind you, "where is (child)?" "(Child's name), where aaaarrrreeee you?"
Wear a hooded sweatshirt with a draw string and make your head disappear as you tighten string, ask child to help to get you out.
Bubble gum -- 4 out of 5 dentists recommend chewing sugarless gum between trials -- just kidding but a big bubble with a big pop is a big reinforcer for most.
Hand grenade deliverance of primary reinforcers -- instead of giving an M&M, pretend to send it thru the air with a whistling sound until it gets to child's mouth then explodes (ie you make exploding sound).
Smell feet with dramatic "p.u.!!" and pass out on floor. Most children will proceed to put their feet in the proximity of your nose real soon.
Put child on table for some break dancing. Lay child's stomach on table w/head toward you and feet away. Put left hand by feet and right by head to generate a pretty good right moving spin.
Make child fly on your feet, then say "it's Barney's turn" and make Barney fly on feet, then child again, etc. (bonus--intro to turn taking)
Pick up telephone – "it's for you, (child)" -- add in dialog.
Say "raise arms" then tickle.
Have child push your nose and have your tongue come out -- pull left ear, tongue goes right and vice versa.
Make Barney, Buzz or Woody doll do trials.
Look for the "tickles" – "Where'd they go? Oh tickles, come out. Wait, there they are!" then find the tickle spot.
Turn table to side with legs toward you, hide until child stands up to find you, then either roar or act scared.
Disco -- "I hope I don't drop you..." with child in arms, then pretty low to floor with "whew! thank goodness"
The table is a tent when you put a blanket over it, crawl underneath in chase mode or hiding.
Swing cardboard in front of child to create wind.
Put socks on child's hands then say "do this" and clap or other wacky commands.
"Oh you want a (food) in your ear? Nooooooo. In your nose? Noooo. On your head? Nooooo. Oh, in your mouth!"
Put child on lap "Mr. Froggy's sitting on a rock, along comes instructor and the froggy goes kerplop!" throw child on couch or beanbag chair.
Thumb wrestle
Sing Barry Manilow songs "Copa cabana" brings out the dancing side in us all...(C'mon, admit it)
Give raspberry's to the belly and/or fake tickly kisses to the ticklish part of the neck.
Hair Torture -- lay child down and gently sweep your hair over their face with "oh, no" or whatever thing to let him know it is coming.
Pillow fights

The palm as monster. Draw a monster on your palm. Use other hand to hold wrist of monster palm so it can't get you. However, we all know monster palm is stronger. elicit child's help to get rid of monster palm.
Have child feed you.
Do dance from ‘The King and I" with the dance where you just walk one way, then turn your body and cheeks and walk the other way.
Put tape over your mouth and try to talk, or pretend you're trying to keep your hand from covering your mouth but can't.

Line your chairs up next to each other and go for a car ride. Seatbelts on. Check left and right for traffic, beep the horn, etc.

Hit child's chest (gently please) with alternating palms so they can hear the funny difference between making a sound with reverberation.
Play kick the can

Imitate child -- child says uh and puts hand on table and you do. After a while child realizes he can run the show in reinforcement.
Elevator rides -- pick him up -- "First floor!" -- higher -- "Second floor" -- "Do you want to go to the third floor?" Then "Oh no, the elevator is going sideways!"
Chair rides -- "Fasten your seatbelt! Hold on to the chair!" Begin to lift chair off ground slowly. If child is fearful, go slow, but keep pushing with an eye on his face -- you may be amazed at how quickly he'll ask for more. Warning, this can result in injury to either of you -- only for the strong!

Also learned from a master, the face pump-up -- "Pump me up!" (mimic two-handed bicycle pump while inflating cheeks). Now you can't talk, but hold his hands and have him POP! your mouth. Next time, pretend you have a leak and have him plug it.
Hot hands -- his hands on yours, he has to pull them away before you can slap them.
Hand game -- hand over hand over hand over hand -- flat or on a pole, as you would do when choosing 'firsts' with a baseball bat.
Crack an egg on his head -- no, not a real egg! -- one fist on top, hit it with the palm of your other hand, then both hands 'dribble' down his face -- yuk!
Borrow science tricks -- baking soda dropped into vinegar makes a nice fizz!
Musical chairs or silly dancing then FREEZE! when the music stops.
Borrow magic tricks -- pull a candy out of his ear.
Electroshock (simulated please!) -- use your fists as 'shock pads' anywhere on his body -- or have him do it to you and get very silly.
