Ditto to the pp - your lo is still very young and right at the beginning of his solid food journey, and even if he loves his solids foods, what he actually needs is milk, milk and more milk!
At this age, milk has all of the nutrition a baby needs, solid food really has few of the nutrients he needs for his health and development, so you introduce them just so he gets to learn about different tastes and textures, and to develop his oral muscles and skills!
He needs to fill up on milk, then you could offer him a small amount of solid food just after his milk feed, so that he's digested a bit of milk to make room for a bit of solid food, but not so he 'eats' too much and then isn't hungry for his next milk feed!
Once a day, probably after his mid-morning bottle, is a good time to offer him this solid food - you do it early in the day so that you can keep an eye out for any allergic reactions throughout the day, and so that if his tummy doesn't cope well with what you offer, it doesn't disrupt his night sleep too much!
If you are offering your ds significantly more solid food than this, or more often in the day, I would seriously consider reducing the amount and frequency until his milk intake increases again!
HTH?
