I did BLW with my son and would definitely do the same if I had another. We started in the winter and it was easy when preparing our dinner to cut stick shapes of potato, parsnip and carrot that he could hold easily when roasted. He would have a finger sized piece of pork or whatever to chew and suck as well.
Also plain cooked spaghetti or noodles (hilarious! it turns out that sucking long strands of spaghetti through your lips thing is intuitive
), slices of fruit (I would microwave wedges of apple until they were slightly softened, he would spit the skins out), slices of pitta bread with humous or avocado. He really liked crusty bread so I would give him lumps to dip into homemade soup made from tinned chopped tomatoes simmered with a few handfuls of red lentils, mixed herbs and loads of pepper. For breakfast I would give him thick porridge with grated apple and cinnamon or mashed banana, toast and cream cheese, or rice krispies mixed with a bit of yogurt, he mostly ate it with his fingers but would mess about with a spoon as well.
Basically he ate the same as us. I have never cooked him a separate meal to us and he has never had pureed food. I don't have any issue with it at all, there has just never been any need.
I used to put a tablecloth under his highchair so I could hand back food he had dropped, or shake it over the bin.
You have to be patient though. It takes them a while to get the hang of it (some longer than others) and you don't have any control like you might if you're actually putting the food into their mouth yourself. And I didn't notice him BFing less at night for quite a while.
About the gagging and choking; remember gagging is not a bad thing, it is the defense mechanism that stops them from choking. If you're nervous though, see if your children's centre does an infant first aid course. I went to one that cost £3 and it was brilliant. Also remember, a baby can just as easily choke on liquid or puree.
You can get info and swap ideas with others on the BLW forum.
Good luck. And sorry for the essay
