Hi Martina! Welcome to BW! I bought the BLW book which gives some good info on getting started if you still have questions after your post.
Just a heads up- F will prob gag on some food. Babies gag reflux is near the center of their tongue so if large pieces get to that place, they gag which is their way of moving the food back to the front of their mouths. It is not the same as choking, and you don't need to do anything! Choking is when they get food stuck and can't breathe. BLW is supposed to make choking LESS likely as the lo's learn to chew first (versus swallowing mushy foods, then learning to chew later).
It was recommended to me to start with fruits and vegies.
You want to do big pieces- so when you give F the pear, give him the whole pear so he can really get ahold of it. With fruits I give the whole thing on apples and pears. I give him half a banana. You can roll foods in things to make them less slippery. I haven't needed to do that with T yet.
With the veggies the food needs to be in a stick shape so that F can grasp it and still have some sticking out of his hand. Veggies steamed or roasted in the oven are good.
Meats are good stewed or slow cooked so they are juicy and tender. So far T's favorite foods are apples, pears, bananas, carrots, and sweet potatoes.
If you want to do something mushy, you can give them a preloaded spoon and let them put it into their mouth, but it is really not highly recommended. I do it anyway since I need to get some carbs into my little guy and I am avoiding wheat and other potential allergens.
If you want to do bread, toast it so it doesn't get too sticky in their mouths.
Cut grapes or cherry tomatoes in half so they don't choke. Wait on more difficult foods like lettuce or anything sticky.
I usually give one piece of each food to start so it doesn't all wind up on the floor. He doesn't eat everything at every meal. Sometimes he just plays with it. Other times he eats a lot.
Here is what I offered T yesterday (he didn't actually eat all of it!)
Breakfast: oatmeal with cinnamon and banana
Lunch: chicken, carrots, apple
Dinner: rice pasta, cauliflower, green beans, pear
HTH!
