One of the main concerns of a kid regarding his/her Halloween candy will be to make sure it doesn't get eaten by others (e.g. siblings, parents, etc.) or thrown away. You can make an agreement ahead of time that your child only be allowed to eat a certain number or amount of candy per day. This can be stated as a pre-condition to your agreeing to allow him/her to go trick-or-treating.

As long as you promise to keep his/her candy separate from other candy, in a bag or container, this should work well. Depending on the age of the child and his/her level of responsibility, you may need to keep the candy out of reach, and only bring it out once a day as agreed. Otherwise, with a responsible child, you can leave the candy somewhere accessible, but remind him/her of the one candy per day agreement periodically, as needed.

Tell your kids a tall tale about the Halloween Witch (or fairy). Like her cousin the Tooth Fairy, she sneaks in on the night of October 31 to spirit away candy--and leave a special toy or other gift in its place.

We put it away so the kids can't get it and they get a treat when we choose, usually after dinner. That way we've made sure they have ate healthly during the day. We let them pick the treat of their choice. By limiting it, they don't get too much all at once and they also look forward to getting it. We also only go to a few houses so we don't end up with tons of candy.

As a little girl, I only went trick or treating on 3 occasions in my life (insert sad violin music here), when I happened to be with my aunt in the US. Other Halloweens as a child I grew up in Mexico, at that time there was no trick or treating there. I remember my American aunt had a good system for when I want trick or treating with my cousins.

At the end of the candy gathering, we would all review what we got, she would check the candy for possible tampering, throw out anything suspicious. We were each allowed to select 2 of our favorite candies from our own pile to be eaten at our choosing, then she would give us a few minutes to barter and trade amongst ourselves with the rest of the pile.

Then she would make sure we all got reasonably even piles, so that none of us had more than the other, she would then have us draw with permanent markers our name and a little design on a ziplock bag, there we each placed our candy stash, and she would give a daily allotment out of our own bag for the next few days.

It made the process fun for us as kids, we never felt restricted, it extended the fun of Halloween past the actual; trick or treating and as far as I remember none of us ever got sick for eating too much candy.

It's all about candy rationing!

I always supported the system my parents used. After they inspected our candy, first my sister and I were allowed to dump it all out and do a "candy swap", trading with eachother for all our favorites. Once the candy swap was over we could pick 4 candies to eat that night. (That's a ton of sugar, but it's one very special night out of the year!)

Then each day my mom would stick a tiny piece of candy in with our healthy lunches (it was always a surprise). And each night after dinner we could have 1-2 pieces of candy. The rest of the time our candy stayed on top of the refrigerator (and seemed to diminish some time after we went to bed. I think my dad had the munchies).

So basically keep the candy where you can dole it out, allowing your kids to still have their own "candy piles" and choose which one they want. It makes the loot very special and fun, but without over-sugaring them.

Remember, it's only once per year!

Happy Halloween!

Hide it.

I have to do this every Halloween. My son is ADHD and he literally craves sugar. He's very compulsive about it, so I hide it from him and then dole it out to him a little at a time when I know he's not too hyper and it won't ruin our night.

This way, he gets a little treat every now and then, and doesn't go through all the candy at one time.

i give my child either one big thing or one small thing for each hand. and this only happens once a day... by about day 3 or 4 she's forgetting to ask about her candy and we eventually end up throwing most of it out.

To prevent from your kid getting to much candy and eating it all after he/she comes back. cook dinner or something that will make then full. tell hem they cant leave without eating it all there food. that way when they come back they dont eat a lot.
what you can do so they dont get a lot of candy go with them but walk slow and they want you to go faster but you tell them before you go trick or treating that they had to be with you at alll times. you can also take breaks while walking.
you can also pick from the candy saying this not good, this one is rotton but you actually just pressed it really hard.
make sure they brush there teeth

Unless it's going to be physically damaging to the child, I would just let them eat it. It's only once a year, and it's not likely going to cause any real harm. On the other hand, trying to control every bite they eat, and when and how they eat it will cause psychological harm that may cause them to overeat when they are older.

My mother used to make me sit at the table in front of cold food after supper if I didn't eat it all. Now I never eat the last bite of the food on my plate. Denial of anything during childhood can cause damage that goes well beyond a temporary sugar high, stomach ache, or maybe a cavity or two.

Why offer excuses? Just set your limit and stick to it.
