1y6m constipation

It started around early July. It was bad but she managed to poop after we gave gripe water (dont actually if coincidence or really worked). Then until now, her poops are a mixture of hard small rounded stools + normal stool. Today, it has been 2 days since she pooped and it seems hard for her to pass motion. She's been squirming but nothing comes out. Any advise to share? She's on solids and formula. Her appetite seems okay, eats brocolli/carrot and fruits.
