15 month old throws food


Hi Everyone. I'm sure this isn't uncommon, so I decided to post to get some ideas. My 15 month old is a great eater but I've noticed the last few months she throws food off her highchair. We have a dog who is eager to catch everything. Well anyways it's gotten really bad this past week where she is now throwing almost everything I put in front of her. Any ideas as to why or what we could be doing to discourage this behaviour? So far we have just tried to ignore it and not give any reaction. Thanks in advance!
