Doubt on feeding solid foods to my baby.

My baby has just completed 7 months. Till date he never tried ragi, wheat, rice etc. as porridge.From 6th month mid he used to have cooked vegies and fruits like potato,dal,peas,banana.Also he used to have papaya,mango,orange,etc. as juice and as whole.My doubt is regarding his feeding style.Is this a healthy diet for him as he is too small to have such a big digestion process.And is there any problem that I didn't gave him any cereal porridge? Speaking about my baby,he has got a normal weight.He also has a good breastfeeding habit.He loves food.Also his developments are a little bit faster.Now he has 2 tooth,he can stand and walk with support,he'll sit independently (although not balanced),he'll crawl nicely...my only concern is about his food.Please help me and suggest me how to feed my baby so that I'll be tension free and he'll be healthier
