We used these when DD was little: http://www.amazon.com/Munchkin-Click-Lock-Fresh-Freezer/dp/B00AA6LQKM/

She loved them a lot! And now we use these:

We have the larger Zoku, but our main freezer doesn't seem to get cold enough for it (no trouble for the smaller molds).

I hate the plastic ones. We have one like this one

We have the ones with the straws to aip from as they melt. Worth the extra money....a lot less messy. My son eats Popsicles everyday (frozen green smoothies!) And these are the best!

We use paper cups. Then defrost and peel paper. We use plastic knives in the middle. A stainless spoon works too

I heard that stainless steel was better than plastic but I haven't gotten any yet.

I have had some from Target for a few years and they do fine.

I bought mine from IKEA and they have held up well. Super cheap too.

Anyone have popsicle molds that they love?
