My Dad and I made Jones a pikler triangle for his birthday. The kid loves to climb so we thought this was a great idea. Boy, does he love it! We went off the plans from Montessori in Real Life and adjusted along the way. Thankfully my Dad had all the tools we needed and the knowledge of how to do this.

(If you are interested in buying one, let me know. My Dad is great with wood working and may start selling them!)
