We started with metal cutlery at 9m.... Suctuonless plates just need a practice, put a couple of pieces of food on it and slowly your LO will learn We started to use porcelain/glass dinnerware, just the small versions to practice
Mine uses small metal cutlery and a small ceramic plate. We've never used suction ones. They just learn not to tip them over the same way they learn everything else really. You've just got to give them a few goes at it. I do have a few plastic spoons but they are harder for her to use if she's feeding herself, so I try to avoid them.
We use the ikea bowls and plates. And use kids metal cutlery, we havnt found them unsafe at all. Tend to use plastic spoons still just as we have so many of them and they are easy for little one to feed himself breakfast x
