7th month old poop question - is this constipation?

Not sure if this qualifies as constipation and requires treatment of if it's normal. My 7 1/2 month old was exclusively breastfed until 6 months. We started solids gradually and he is now eating 2 meals a day which each consist of 1 TBS (dry) oatmeal cereal mixed with breast milk, 1 once of a fruit such as pear and at dinner an additional 1 ounce of sweet potato. His stools have been getting progressively more and more solid. Now, they are often formed and somewhat small. They are not hard - they are still soft but definitely hold their own form. He doesn't appear to be any more distressed than usual when he goes. He has always grunted and strained even when he had liquid poo and he still grunts and strains. But he doesn't cry, and he doesn't have any torn skin or anything like that. In terms of frequency, it's still at least once a day, sometimes twice. So, is it constipation or is that normal? Thanks!
