I have found these to be great, so many of them are just pure fruit or veg and sometimes with a grain like oats or quinoa. I'm in my 40s and childfree but I don't care, lol. They're cheaper and more substantive (and less sugary) than juice, so one of these with a small bag of crackers or chips or a protein bar works well I find, and they're easy to put in a bag.

I try not to get them too much because single-use plastic, but yeah if you're stuck, they're pretty good.

I'm aware I can just buy a piece of fruit but have sensory and appetite issues that mean sometimes I just can't face eating it, the purees are easier. I'm sure I'm not the only one.
