The thing is, you have to look at the big picture. And taking a break now might be the difference between him getting the hang of it soon, or having problems later on, kwim? Give it a few days to start where you do very little. Definitely put the spoon away. If he is watching you guys eat then of course offer, but if he's showing no interest then don't bug him about it. When you start trying again will depend on him, and you. You'll have to get an idea for that, but I'm sure after a few days or a week you can at least offer, and I would offer only finger foods. If he says no, put it away and wait again. Then keep offering, but don't push. You want it to be more like "oh you're not interested? Ok, no big deal! maybe later then" and not "why aren't you interested already? you should be!" Kids pick up on this stuff, yk? It's ok, you will get there. When I look at F and now he is eating now, he is eating the way many moms expect their kids to eat right off the bat. It's like he's starting new, but he's 9mos!! He just needed that much time to be ready. I put the spoon away as soon as he started refusing. Then I always offered finger foods, but TBH he didn't even want that. If he didn't want to sit in the highchair, I took him out and he either sat on my lap or once he could he sat on the floor (I swear he spent every meal in my lap for months!
).
Having a tricky eater has taught me so much more about solids (and patience!). T was so easy, well he was textbook. Even eating was textbook with him, he followed every natural progression the way the books said, from single purees, to different combinations and textures, and finally to finger food. But with F I can finally, truly understand why some babies need to wait to be ready, and why it takes them so long to get it. Remember you still have so much practice time before a year when solids are 'supposed' to be the main focus, and a lot can happen in even just a month's time.
BTW, I don't believe there is such thing as a square one.
