I found a really easy way to fill your ice cube trays with your pureed foods! After pureeing, put your food in a large ziplock bag and zip the top. Then cut off one of the bottom corners and use it like a cake decorating bag to fill each hole. No spooning and making a huge mess! It was so fast! I cut a largish hole (about an inch or even more maybe). So far I've done it just with sweet potatoes that have a stickier texture and I tend to make my babyfoods a little thicker and then thin them down later if needed (but my babies like them a little thicker). I'll let you know if it works with other foods, but so far we've only had cereal and now sweet potatoes here.
Just thought I'd share!
