There's at least one missing, Spanish for Children, fresh out from Classical Academic Press (different from the Spanish for Children listed at this site), but it's suitable for a bit older children than the OP's. Here's a list of most of the common homeschooling Spanish programs. These include walk like, act like, sing, stand, sit, close, open, put on (clothing), take off (clothing), turn around, stick (out your tongue), touch, scratch, stroke, jump, and walk. Keep your child on track with printable reports and lesson progress data. TruAccent® speech-recognition technology listens, analyzes, and corrects your childs speech throughout the learning process. With Rosetta Stone, kids can practice early reading English language skills, while learning Spanish at the same time. These are typically integrated into the lessons. Rosetta Stone teaches language the natural wayno translation required.

Topics covered include: alphabet through ñ, numbers to 20, clothing, body parts, colours, animals, basic descriptors (man, woman, tall, short, fat, big, small, etc), simple phrases like 'hace frio' and 'hace calor.' A number of verbs, typically in the imperative, are covered as well. Rosetta Stone’s Dynamic Immersion® teaches you the language, not just the words. The conventional 26 letters are all there, with only three more you’ll have to learn: ch (chay), ll (elle), and ñ (eñe). Download lessons to do everything offline. The standard Spanish alphabet is also an almost exact match with English. Perfect your pronunciation with instantaneous feedback. Learn intuitively using our proven immersion method. From day one, you’ll: Stay focused with a personalized learning plan based on your motivation. The one drawback is that only Level 1 is available, so you only get halfway through the alphabet. Rosetta Stone has taught millions of people new languages, and you’re next.

I highly recommend Puertas Abiertas as an introduction to Spanish.

Is there something else in approximately the same price range ($200-250) that you'd recommend?
