Making baby food

My LO is 4 months and I will be starting solids around 6 months and I plan to make it myself. I want to see about making it now and freezing it so I have it all ready when she can start eating solids at 6 months. Just wondering what you suggest I start with and how much breastmilk I should use? I have done some research but not really finding exactly how I should be making it with breastmilk, and how I can store it. Any tips would be fantastic, thank you!
