My 3 y/o granddaughter loves her preschool box! Her 2nd box was delayed and I heard about it. I will definitely be renewing.
She is a bit advanced, likes to learn and be stimulated so not sure if this would work for the average 3 year old but it is perfect for her (she will actually be 3 in a couple weeks).
My DIL loved her first box; I am excited to hear what she thinks about the next one!
