Tmi 6 month old baby poop

It’s been a week of starting solids initially her poop was normal but now last 2 days it’s been like this

I did start with zucchini that was fine

Last 2 days started with butternut squash the first day jus by itself then last 2 days mixed with Prunes

Is that why the poop black because of the prunes

Or should I be worried

I think my baby is constipated too

How can I help her pls help mommies
