A lot of the mums on this thread found that Spatone or Floradix worked a tonne better than iron tablets at getting their Hb up (and they don't bung you up like the tablets), so do check those out.
I'm sure there was someone that was borderline GD but can't remember who. But do read here.
Finally, steriliser. Personally, I didn't see the point of sterilising things when he was 6 months + because he was grabbing god-knows-what and putting it in his mouth, and you can't sterilise everything. If you're exclusively breastfeeding, no you don't need one. I never had one until I started expressing for return to work, and I've since discovered that you don't need to sterilise with expressed breastmilk like you need to with formula, so I started just doing a hot, soapy wash.
