Firstly, she needs her head read - I have never ever heard of a GP speaking such bull**** to be honest. I know there are some iffy ones out there but that takes the cake. And the stuff about thrush is just rubbish. I would recommend you get some probiotics into you. Start off with fast-tract and then move onto In-Liven - both are 100% organic and are perfectly safe to use while BF and you can even give them to your little girl too. I swear by it - as do many other BellyBelly members. You can purchase them here ONEgroup and some great info about both Fast Tract and In-Liven is here https://www.bellybelly.com.au/misc/mivitality-inliven
