OK so the OhBaby black market is one well-oiled machine when need be!!  The worst case scenario won't happen because at the most I'm 40mins away and you wouldn't completely run out before making sure you had some more anyway.  Take a deep breath - and nah, I won't try to make light of it because it's a rediculous system you have to go through just to get the one and only source of nutrition for your baby - rediculous.  A Chemist told me that a SA# can be applied for urgently via fax if need be, and should have it that day or the next - so while yes, I waited weeks for ours and tore my hair out each day, what I learnt from that was not to take 'no' for an answer and ring them and NAG, because you might find out after a week of hearing nothing that the form has just sat on someone's desk that whole time.  Nag and plead desperation, girl!  Also, try not to be too receptive to the 'lets try something else first' idea if that's what's pitched to you - you've got blimmin good reason not to, especially for a bub Greer's age.  If you're not feeling up to getting stroppy invite me along to the appointment!
