Best of luck with sleep school ladies.
On the wind side - I know how much you want to bf, I did too - I had cut out most foods but Hilton just couldn't handle my milk. Have you tried a straight formula feed to see if it helps. It's great you are willing to give up more but at some stage as mums it can become too draining BF'ing, sleepless nights settling our babies and watching our babes go through the pain! I was drained with no sugar, colic foods etc but as hard as it was stopping giving him breast milk was the best for both of us and was an instant change - still get a little wind sometimes but everything changed for the better! Sometimes you have to say enough is enough as cutting things out is admirable but if you are starting to feel drained stopping for your health is just as admirable plus you can take stock in the fact that you have breastfed for as long as you could! Food for thought! And big hugs!
