How to get my 6 month old to eat more solids

She had her 6 month appointment yesterday, and she’s losing weight. She was 17 pounds and now she’s down to 15. She doesn’t like ANY baby food that’s fruit flavor, and there’s only a couple vegetable ones she does like. When she’s hungry, she won’t take anything but a bottle. I tried to feed her some mushed up scrambled eggs this morning and she wouldn’t eat them.. feeling like a bad mom at this point ☹️💔 any help is appreciated
