i just picked up some plum organics...they are the baggies of pureed baby food and the kids can squeeze them in their mouths. i wanted to try and give the kids this as a snack from time to time. any tips on teaching them how to squeeze them into their mouths? my one son just sucks it through the hole like a straw. the other squuezes them and a RIDICULOUS amount of food comes out, lol.
