I have no idea why you need a steamer? Or special trays?
I do have a smoothie maker that cost me $22 at Target (on sale..an off brand), and I love it and use it for other things too (smoothies, food prep, etc). I make baby food for my daycare. I mostly do what I call "Must go's" for baby food. Whatever the other kids don't use for a meal, or what is left in the fruit bowl on Fridays..or when it starts going ishy. Like a half banana..or a one person portion of green beans, etc. I whip it up (takes me about 60 seconds), and either feed it at that meal, or freeze it if its a bunch.
Then I will do a base of foods...2 or 3 sweet potatoes goes a long way with a 5 month old just eating baby food. Or 2 season squash on sale. For someone like me who buys alot of baby food (or used to), I have saved alot of money, had kids eat a better variety of foods (they DO like it better..I have over 20 years experience with a variety of kids...the overall experience the last 4 years has shown me that they are all better eaters with the home made stuff..even if it comes from canned fruits. I will assume the flavor is better..less processed??)
And if you are eco-friendly...think of the trash you create with baby food containers (even with glass that can be recycled, they have labels and covers that are trash). Plastic is worse of course.
Many of my daycare kids are not on baby food long, altho by USDA standards, I am required to OFFER it to them until their first birthday. But this way I get to choose the consistency. My now 10 and 11 month olds in care self feed, but I do give them cereal with a bit of chunky fruit or veg for lunch and breakfast, as required for the protein in it.
Just my thoughts and experiences.
