Oops, we must have been typing at the same time, sorry.

Anyway, if the baby has been crawling for months and is trying to walk, she is definitely old enough for a wide variety of foods (and drinks - see kefir above), so you do not need formula for her. She is too developed for that.

You can buy a package of shredded cheese at a supermarket and put little piles on her plate (no work and safe, unlike cheese cubes and cheese sticks). Again, just make sure that you are not feeding her anything low-fat or non-fat. She needs all the fat for her brain development. There are packages with coarsely shredded cheese and finely shredded cheese - if you combine a bit of both, that would be a very good sensory experience for her. Plus, color - white cheese combined with orange cheese would look interesting and appealing to her. And I would cook steel cut oats in a thermos (virtually no work effort involved) and give her to eat at breakfast time. Another no work effort involved food is canned salmon which can be bought without bones and cartilage (at least in the US) and then easily mashed. Read up on fish safety for babies, though - the recommendations keep changing.
