We've had HEAPS of constipation probs. Caitlin started on Nurture then switched to Karicare (she was bunged up with both). The only thing I can honestly say works to clear her out is a few teaspoons of apple/pear baby food.
If you're not keen on solids yet try a bottle of warm water between feeds, 1/2 teaspoon of brown sugar in 100mls of warm water, cirling the legs (like riding a bike) or massaging the tummy (PM if you want details) if all else fails try a chiropractor, that always clears out Caitlin.
Good luck! I know how awful it is
