Amazon is currently offering a 30% discount on the LEGO Duplo "Caring for Animals at the Farm" set, bringing its price down to $34.99 as part of a back-to-school sale. This particular set is recommended for children aged two and older, featuring six animal figures including horses, cows, a chicken, a sheep, and a cat.

The LEGO Duplo line is designed for various developmental stages, with sets available for ages 18 months to five years. The "Caring for Animals at the Farm" set is aimed at the 2+ age range, offering more figures than sets intended for younger toddlers. The smaller age ranges are typically recommended for children who are developing their fine motor skills and are less likely to attempt to ingest smaller pieces.

In addition to the farm set, Amazon also has a different LEGO Duplo box on sale that is suitable for younger toddlers aged 18 months and up. This set includes 80 pieces and three wheel bases for constructing simple cars and structures, intended to encourage early creativity.
