Comparison is the thief of joy!
Milk (FF or BF) should be the main food source of nutrition until 1 anyway, so don't panic. Has she had her 10m development review with the health visitor yet? You could always give them a call for reassurance if you need.
Do you eat with her, and the same food that she is eating? Sit with her and let her see you eating the same food. Let her play, if she picks it up, great! If she licks it, great! If she throws it, great! If she feeds it to you, great! She's learning what she can do and what she likes and doesn't like. She's learning textures and how to hold things that feel different, sticky slippery, firm, soft.
Take the pressure off yourself, don't make separate meals just for her (in case you were), let her choose something from your plate to try. Take the pressure off her, don't expect her to eat it. She will when she's ready.
Keep offering different things, revisit things you've already offered, eat with her. Let her explore. And offer her milk after solids.
You've got this ☺️
