6 months....No solids yet

My baby girl is 6 months and 3 weeks old and she just does not want solids at all. I've tried avocado, peas, sweet potatoes, banana, applesauce, baby yogurt in vanilla, banana, and mango flavor (def hates mango and bananas) and just no luck. She will taste it but then just refuses it all together. On the foods she really hates, she will gag. She has been 100% breastfed up till this point and that's pretty much all she wants right now.

Any advice or suggestions? I dont want to force it and make it a negative experience. I did try Rice cereal with breastmilk and she turns her nose up to that too. And after eating a solid she gets diarrhea so I'm think may e she just isnt ready yet. Let me know ladies!
