I second prune puree and just sips of water with eating. We've got the same issue. I remember my eldest was like this too and he digestive system got used to is eventually
Prune purée and also water during meals and throughout the day too that is helping us! X
As a rule, add flaxseeds and chia seeds every day to keep things regular But to get things going use prune puree or lactulose if that doesn't work
Same here, prune purée didn’t help so we are on lactulose now, it took few days to work x
