They are still learning to chew
Chewing is a skill, like walking. Some foods will come back out while they practice.

Softer, and a food they manage
Stay with softer foods and a familiar one they manage well. Spitting a hard piece is a reason to change the texture, not to scold.
Practice happens at a table, with you there, not in a moving car.
What practice looks like
A mash they swallow, a soft lump they move around, a piece that comes back out. Offer the familiar food so they are not hungry while they practice.
Hard practice foods are how meals become frightening. Keep the practice soft.
When to ask for help
Coughing, frequent choking, or distress at every texture is a reason to talk to your child’s doctor.
This page cannot tell you whether a chew is on track. It can tell you to keep food soft and stay nearby.
A sentence you can say
“We’ll stay with soft food while you learn.”
