If you have Facebook there is a really good group on there ‘ baby led weaning for beginners and beyond.’ My lo is almost 7 months and between that group and the app solid starts I am able to introduce solids to my baby.
Start with one at a time and watch for reactions, you can add more foods as baby tries them and you start repeating foods that you know are safe. A plate of three different foods in the beginning can be stressful for baby - mine did not like it one bit. She did much better starting with one, then two foods at a time, then small amounts of our meals around 9 months, then full meals around 10-11 months.
Try solid starts really good app !
