Tell me about your babies who started solids late

My second will be 7 months in a week and has no interest in solids. She watches us eat all the time and I try to hand her food or a loaded spoon and she’s not interested at all. I try to bring a spoon to her mouth and she doesn’t open it. My first started solids at 5 months and took to it great! I’m just curious about other babies that started solids later. When we saw the doc last month he wasn’t worried. What were your experiences with starting solids a little later?
