Breastfeeding/ solids ??

So I know every baby is different but lately I've been wondering about a few things.

My 7 month old, (8 months on October 3rd) is a happy, healthy , always hungry baby boy.

I breastfeed exclusively since birth.

Lately we've been giving him 3 meals a day since he was always fussy and never getting full no matter how long he stayed on the breast.

With the baby food, we do fruit for breakfast , a fruit/veggie mix for lunch, and a veggie with oatmeal for dinner.

He gets juice with his meals, sometimes milk if I think that he's still hungry after his container of solids.

He gets milk everytime He naps (2-3 times a day) and milk to go to sleep at night and then 4-5 times a night when he tosses or turns/ wakes up.

I'm just wondering if him eating solids thru out the day could cause any damage ? I know this sounds crazy, but I worry a lot lol.

**** and to addd: he does eat "tablefood" w/ us, he chews very well and loves bites of our food. He'll even yell at us if we don't give him a bite lol ***
