I am also borderline anaemic. I went to the doctor after feeling like garbage for 3 months (but is now 6 months). We did a blood test and I was told I was borderline anaemic. You certainly don't have to give up breastfeeding. I was put on tablets called FEROS-GRADUMENT C. They are high iron tablets with vitamin c and they come in a one month supply for around $15 at your chemist. Another girl at my mothers group is the same and taking the same ones and we are feeling much better. You need to take them for around 3 months and I called Mothersafe and they said they are completely fine to take and will not harm (or constipate) bubs. (Eating meat and veges etc is great but if you are almost anaemic you will need a bigger iron supplement than your diet can give you).

Good luck!
