Constipation- 8 weeks old

[ThreeAfter30]

My baby girl is 8 weeks old and is having a complete nightmare trying to poo. We are lucky if she goes once a day and even when she does its soooo watery. Poor child just cant seem to go today, ive even given cooled boiled water/prune juice mix as advised by HV. Cant remember my other 2 having problems going.
Does anyone have any tips on how to help her?
Ive tried tummy massage, bum massage, bicycle legs and warm bath, nothings helping her at all :(

Are you breast or bottle formula feeding?

Have you tried dufalac?

Is she actually called constipated? Just checking because babies( mainly bf) don't always poo incessantly. My DD only opened her bowels once a week or so but her stools were soft ie not constipated. Some babies also make a huge fuss, writhing and squirming before bo, if their stools are soft and reasonably plentiful they are not constipated , they are just getting used to the feelings involved in bowel opening.
If your baby's stools are hard then please ignore my thoughts!!
