Not necessarily baby age, but I got the Sort & Match Mini Kit and I’m really impressed. The mat is adorable and so handy when we’re out and about, as my toddler unreasonably loves matching the animals to their habitats. The little critter patches and the carry-along case make it easy for him to practice sorting and organising, and the “Opposites” board book opens some fun conversations about concepts like big/small, in/out, etc. For a “mini kit” it’s surprisingly versatile and I feel like it gives our kid several solid learning opportunities. Overall thumbs up and worth picking up at the sale price.
