Lego is really tricky stuff. Toby loves it but treats it like a jigsaw - so he builds it and then has to immediately put it away!
Just look at the concentration needed here to find the correct pieces, and then fit them correctly as per the instructions. It takes a lot to push the pieces until they click too. It’s such difficult fine motor skills, but a fun way to practice. Toby is so thrilled at the end!
