Ever since I started giving my baby solid food (6m+ now), he doesn't rly want to drink milk. Even before the solid food started, he only drank when his favourite movie was played, when we were in the car, on when he was really thirsty. But now, it's even harder because he is full with solid.

The thing that worries me is that he is constipating now even though I give him apple & banana puree, and try to feed him water after each spoon of solid food like veggie & chicken porridge. His poop is hard like pebbles. When I give him enough liquid, he poops just fine. Sometimes when he doesn't wanna drink, that's when the hard poop and constipation come. What should I do?
