I'm at my wits end with C and her food throwing! I just simply don't know what to do about it. Every single meal time she throws her food onto the floor. This week we decided to be more strict about it (because it's getting worse by the day) and we now take her out of her highchair as soon as she throws her food and put her down on the floor for a few minutes. We obviously tell her "No, no throwing food" and ask her to put the food aside if she doesn't want it. Sometimes she does this but usually not. What are your suggestions? What do you do? It's obvious that she's hungry because she will eat after awhile but it's just so much fun to throw it apparently!

ugh!
Re: So we've discussed this before but...
D was really bad for awhile. I finally realized that a lot of it was that he really didn't like being constrained in his high chair any more. We have since moved him to a booster at the kitchen table and he really likes eating like a big boy. He enjoys it so much more and we have less food throwing. We also give him a plate and a fork, sometimes though he dumps the food all on the table and hands me the plate. He does still like to share with the dog. I have noticed that if he isn't super hungry or if he is really tired we have more food throwing. I generally take him down, tell him we don't throw our food and wait a little bit before trying again.
Also I wait about 30 minutes after a nap or waking up before giving him breakfast. I have noticed that if he has time to fully wake up and let his tummy realize it is hungry, then he will eat more and throw less.
Nate throws food too. Just here to commiserate. This morning after breakfast, I made him pick up his cup, the rest of a breakfast bar, and clean up the spilt milk off the carpet. That was the first time I've made him clean it up. That's my new plan. If I catch him about to throw food, I tell him to "put it back" on the tray. If he does it, I get all happy and he claps for himself. It's a start.
It's driving us nuts too.
I hate to jinx things, but I think we are moving past the food throwing phase. He does do it from time to time, but he mostly he now picks up the food & hands it back to me, saying "nah! all done!" lol
We used to remove the tray from the high chair immediately when he'd start to throw & of course give the stern, "No! You don't throw food!". I guess this helped, but mostly, I think it was just that the phase passed naturally.
We've moved away from it as well. We also removed the tray as soon as throwing started, so I think that helps. Follow through is key. So is luck.
This is pretty much us, too. It used to drive me nuts because it seemed like all he did was throw food at meals, but I think he's pretty much done with it. I also used to take the tray away and say "No throwing food!" But I honestly don't think that helped. Like bosha said, I think it was just a phase that passed naturally.
Now he only throws food when he is totally done eating and wants to play.
eta: I hope your LO's phase passes quickly and that you can enjoy meals again!
It's getting better around here (but still not stopped completely). Things that I think have helped:
Keeping the dog away from the table. She loves to give him food and get his attention or have him jump up to see her.
If it's just harmless dropping (not throwing) I ignore it. The dog will clean it up anyways! I think this has helped the most.
I give her smaller amounts (like 4 blueberries instead of 30) so that if she does start throwing, then at least it's not as many. If she does start throwing I assume she's full or wants something different.
Sorry, can't help, but am here to commiserate too. DS doesn't throw his food, but he drops it constantly. We've tried taking the try away and doing the stern "Do not throw food" and tell him to put it aside, but it never sticks. I really really really hope it's a phase because I don't know what to do about it. He also likes to drop his sippy cup, which has caused a dent or two in our hardwood floors *siiigh*.
I think I'll try PP's suggestion of putting him in a booster seat instead of the high chair. Maybe he would rather sit at the table.
