Good night? Has anyone used something like this? I want to try it for a while, I'm in another city now and don't want to buy dishes for baby food, when I'm home I want to buy a good set of dishes, who has used what, if you have photos please send them ? I plan to start with vegetables in 5 months, the pediatrician said at 4.5 years old it's possible but I still plan. I know that many will write from 6 months needed ? But they recommend starting around 4-6 months. Share your opinion ?
