In general - have you considered making it? It's actually really easy, and you can freeze baby-sized portions in an ice cube tray. We loved steamed/mashed sweet potatoes for a first food - you can thin with a bit of breastmilk, formula or water if needed.

Travel - carry ripe bananas and avocados. Mash with a fork, or use a spoon to scoop bites right from the fruit.

Sorry I'm not much help on the brands for store-bought. We did use containers when traveling, but it was quite a few years ago and many of the brands have changed.

Baby SLOP!! Local, organic, home made, and sustainable!!!!

We just bought the spoon that screws directly onto pouch. We use that when we're out and it works great.

I like Earth's Best. Stuff tastes like what it's supposed to.

Home made

The pouches are great for travel. You don't need to transfer the food into anything. You just squeeze it right into the spoon.

For trips we did a combo of prepared, jarred food, but also avocados, bananas, and other things you can just buy or take and mash up.

Good nutritionally in terms of suitability for a baby.

Thanks... the pouches are so expensive, it seems... are they easy enough to feed to a young baby? It seems like a toddler could suck them out, but I don't know if we'd then need to transfer into a container and use a spoon?

Good in terms of...what? Looking at the ingredients, I'd go with:
Peter Rabbit Organics
Plum organics

I like the pouches more than the jars typically, but it's up to you.

I'm looking for good first-ish foods for a 7 month old (and, I supposed, later) that I can get from Amazon relatively cheaply.

- in general
- for traveling (we're going on a week-long trip)

Thanks!
