It's all a big learning curve and you're doing a great job!
I did BLW with two out of my three and some of their faves were
*Thick cut cucumber sticks with skin left on - easier for little hands to grip and they can just gum off the soft flesh. They also loved them dipped in yoghurt or other home made dips like guacamole.
*Corn on the cob - LOVED it.
*Cruskits/rice cakes with avocado or cottage cheese.
*Rice - I just used to do a sort of fried rice that was just rice with an egg through it with some peas and baby spinach.
*Thick cut roasted sweet potato, carrot and pumpkin
*Pikelets, plain or with grated apple.
*Lamb chops, strips of steak - they would gum and suck the juices.
*Pasta - any kind/shape/sauce
