Been using this with my 14 & 5 month old grandkids. My 14 month old can play with a whole section. My 5 month old like the books & mirrors. I use 1 section a week, then do a craft a day using 1 part of the section. For example, for the face section we play with the entire section for about 10 - 15 (or less) minutes. Then we craft about just hair one day, the next day we craft about eyes. There are 4 total sections, a good month of activity. If we have more than 5 items in each section, we just craft about the other the following month. I'm excited to start using it with my 2 month old grandson & my 4th grandkiddo.
