We recently purchased the kids wooden growth charts from woodandroom and they have proven to be a great tool for tracking our child's growth. The cards are made of quality wood and are very sturdy and safe. We love that we can make marks and track progress. The cards also serve as a great decorative element in the child's room. Our child enjoys participating in the measuring process. If you are looking for a fun and practical way to keep track of your child's growth, these cards are a great choice.
