We absolutely are in LOVE with these boxes! I recommend it to all of the moms I know with toddlers. My daughter is so excited when a new one comes and spends the next week carrying it from room to room. When we get a new box, we go through each activity one time together so she knows how to use it. After that, she is able to work with them on her own. As a homeschooler, it has been a great way to keep her busy while I work with the older kids. I like the creative themes each month. This month's Dental Health has been a huge hit here!
For reference: My daughter will be 4 in a couple of weeks. This month was our third box. Age-wise, I think it can work for a 2-yr old with a lot of assistance, but is probably best for ages 3-4. (Though her older siblings fight for the chance to try every box as soon as she has tried everything.) I would expect that the activities would be below her skill level sometime between 4-4.5 years, but that doesn't mean they won't still be fun at that age.
We bought a 3-month subscription for our daughter's 7th birthday. Katelyn was very helpful. We ordered past the date to receive the September box, but she managed to get us a September box within a couple of days so that I could wrap it! It arrived quickly and had a beautiful presentation. The box is so carefully prepared, and the pre-measured ingredients made it very easy to bake with a child.
Today, we made the doughnut holes. It was a lot of fun and my daughter already cannot wait for the next box! Her 5-yr-old sisters are asking for a Mix Box for their birthday now!
