I won't give you the full tutorial on how to cook and make your own baby food, because there are LOTS of websites out there that show you that. But here are my top two favorite baby food websites:
Homemade Baby Food Recipes
But I will show you how I freeze and what I use regularly to thaw the frozen food.
When I am finished pureeing the cooked food, I freeze in ice cube trays, and when they're frozen in the trays, I pop out and put in a plastic freezer bag, label the food and date, and stick in the freezer.
Then, each night, I pull out a few cubes for the next day, stick them in the plastic Gerber baby food containers and put in the fridge overnight.
By the next day, the cubes are thawed and ready for my little baby to eat.
So easy! I sometimes make a big batch of baby food at once, or some nights I boil just a couple carrots or just an apple, while I'm making dinner anyway, so it's no big deal.
