Constipation and breastmilk

Does your breastmilk depending on what you eat like less veggies cause your baby to become constipated? I wonder if that’s the cause of my baby’s constipation! That I don’t eat very much veggies and it’s passed down to her causing her to have trouble pooping!? Also what’s normal for baby pooping schedule at 8-9 months? Are they suppose to poop everyday?!?
