Hi everyone... just wondering what everyone uses for dishes/cups for their kids, I'm looking at the Ikea Kalas set... I've heard they're BPA free, but it doesn't say so on the website, just says it's polypropylene. Any thoughts? I really would like products that are free of BPA, phthalates, lead, pvc, and Melamine. I really would like to keep cost down if possible, looking to get a larger set as I have 3 kids that will be using it.
