We didn't BLW, but I make my own food for him, often an adapted version of what we're having minus the added salt, chilli etc. Then puréed or, these days, just chopped/masked (he's 8 months). If there's extra, I freeze it.
When we started, I batch cooked and puréed veg & froze in ice cube trays, dead easy, and far cheaper than jars. Try baking a sweet potato in the oven, and just scooping out and mashing with a little butter - DS loved this when we were first trying him on solids. Or stewed apple, or mashed banana.
I did use the occasional pouch when out and about, but I view them like ready meals - once in a while is ok, but I wouldn't want to eat them every day myself. And some are better than others - the Ella's kitchen ones are all natural ingredients, but some of the jars seem to contain nothing but thickeners/stabilisers etc. They also have a frighteningly long shelf life, which makes me wonder how many nutrients they really contain.
My sister BLW, and it worked for her, but I was put off by the massive amount of wasted food - it's not for everyone. We do fingers foods (toast/veg sticks/fruit) with every meal, and DS is learning to feed himself very efficiently!
