I’m stressing

My nine month old has no interest in solids at all! He gets baby food, breast milk, and water, and that’s all he wants. I try and retry at regular intravels and he either turns his nose up at it or chokes on it and scares the tar out of me. He’s at a healthy weight and he’s growing and gaining like he should. My pediatrician has said that food is just fun until one and is a huge advocate of breast as his sole nutrition until then. I’m stressed though thinking what if he gets to 1 and still doesn’t want solids?!
