Buying boxes of popsicles are very expensive (and not especially healthy) and my little one is addicted to "Eis". He wants one literally 10 times a day. I was hoping to make my own with apple juice or orange juice but I haven't been able to find those typical plastic forms to make them. I asked at ikea and I've checked the local supermarkets with no luck. Anyone have any idea where I can buy them? Thanks
