We got these toys for my daughter when she was 6 months old, and she started really liking them when she was about 10 months old. She still loves them at 16 months, and she is really able to stack them well now. I think they are great for teaching spatial skills. These are a great toy for interactive play with babies - one of the few toys that you can play with jointly with a 1 year old. We got the 27 piece set to augment the 13 piece set, so we can really build!

We have had these for 6 months now. Our girl likes them more and more as she gets older. They don't stick like Legos, but rather loosely sit atop each other. This actually makes stacking easier than trying to fit them together, and still prevents toppling.

My daughter got these for her first birthday. They are beautiful and sturdy. I thought the stick block concept would be great for her but it's still a little tricky for her to 1) stack the blocks so that they "stick" and 2) to demolish them (her new favorite game. Also, there are plenty of blocks to get her started but the set is kind of small - I may be adding to it soon.

My son got the larger set of Sticki- Blausteine blocks when he was 18 months. When he was 2, I bought these to add to his collection. He's 2 1/2 and plays with these regularly. It's fascinating to watch what he comes up with. I find these to be a nice alternative to the plastic building blocks out there.

These blocks are SO cute & colorful!! And so well made! When I ordered them, I thought they were on the expensive side, but they are totally worth it! They stack easily & the building possibility's are endless. We are going to be ordering more!
