i think giving a suppository each time to poo, can weaken the poo muscles (or not allow them to learn to work properly if they are already weak), and so laxatives can be less damaging than constant suppositories.
perhaps you need further investigation just to check that anatomically everything is working ok.
We used to use Nan HA gold but they changed the recipe and it gave my son the worst constipation/runs so we swapped to Bellamy Organic and it was the best. A lot of my friend's also did the same. I did hear that any of the S26 products were know for giving constipation but every child is different xxx
