Query: Great Concept, Poor Execution

My 3 month old son got this for a Christmas gift and I was shocked to find my 3 year old daughter struggles with it. While it says it's for 6 month to 3 year olds, the shapes are too large to fit in the holes (specifically the triangle and star). I thought it was odd that my 3 year old couldn't do it so I attempted and had the same issue. You literally have to find the perfect angle to have the shape fit. Also, once you put the lid on the top of the jar, there's no way a child would be able to remove it. I found this frustrating as my 3 year old asked me repeatedly to open it for her. Had I purchased the gift myself I would return it. Since it's a gift, i'll let it collect dust in the off chance one of the kids will use it again. Don't waste your time.
