Spit out the food or thrust it out (like her tongue is working backwards)? DD thrust food out of her mouth until about 15 months and then just got it (we had an appointment with a physical therapist but didn’t need it). Bottle-fed and I wonder if that had something to do with it and we kept her on toddler formula .

Try giving her only a few bites at a time. But also, I wouldn't even worry about this. She'll learn how much food she can manage.

My kid did this for a while and then magically outgrew it around 2.5. It was worse when we had company for dinner -- even just one person, like an aunt or uncle. One thing that helped a little bit was giving them a board book to look at and then we'd give just a couple piece of food at a time. They were less inclined to make eating into a game because they were distracted by the book. He still occasionally shovels too much in his mouth and spits it all out, but the spitting is just a couple times a week and not several times a meal.

In a high chair. One piece/spoon of food on her plate at a time. Exhausting but she will learn.

18 months DD is my second child. I am trying to let her eat by herself. If she have something she likes she would stuff a mouthful, then spit it out because she can't swallow. Or when she's chewing and somebody happens to put water or new food on her plate she'll spit out the food in her mouth and try the new food. This never happened with my older son.

In general she's easily distracted, she want to play with toy, interact with people while sitting in high chair, we had to feed her in living room where there is no toy, no people around and only one kind of food (usually vege/meat/starch premixed) in order for her to finish at a reasonable time.

Any thoughts?
