6 mth baby Constipation after starting solids

Hi mummy, im facing same issue now. My baby is 8 months old. Not pooping himsf without help of suppository (put med into backside) for more than a month. Do you have any remedy for your baby? I tried giving him papaya/pear/juice but he is not eating much hence no effect.

Try increase fluid and fibre intake! Lots of fruits and veggies.. you can try prune purée too
