Hey Maddismum - My
DS was terrible for wind between about 6-12 weeks, infacol worked for us, but as its not making much difference for you, perhaps try something else, there are quite a few remedies - ask at your pharmacy, they should be able to offer some options. If you think she is constipated a natural remedy is to mix some brown sugar with some boiled water and once cooled spoon some of the liquid into her mouth, it can get things moving downstairs IYKWIM?
Re the bowel movements - is she breastfed? As its completely normal for breast fed babies to go even a couple of weeks between bowel movements, my son went about 7 days once and when he did finally go - whew, it was a corker, and a bath was the only solution HAHAHAHAHAHA
