Subscribing as well (and celebrating that we have this thread - thanks Schmickers! ).

One of the things that confused me was when the physio said to me that I had pelvic instability - was it the same thing as SPD? According to http://www.pelvicinstability.org.au (mods -pls remove this if I'm not supposed to link it), they say the following:
Pelvic Instability has historically been known by many different names. In Europe it is most commonly known as Pelvic Girdle Pain (PGP) or Symphysis Pubis Dysfunction (SPD). It is also known by the medical profession as: Pregnancy-related pelvic joint pain; Posterior pelvic pain in pregnancy; Peri partum pelvic pain; Pelvic girdle relaxation; Pelvic girdle syndrome; Pelvic insufficiency; Pelvic dysfunction; Pelvic arthropathy; Pelvic osteoarthropathy; Pubic symphysis instability; Symphysiolysis; Sacroiliac joint syndrome or Sacroiliac joint dysfunction.
AFM - I had it mildly last PG and so far have it worse this PG. As the others have said, support belt, ice (and/or heat - I've been told both!?), don't walk up stairs/hills/uneven surfaces. Avoid heavy lifting, twisting, bending, turning, doing things standing on one leg, vacuuming, shopping trolleys (they are the PITS!). I've been getting osteo treatment weekly and am about to try physio also. I also have stretches and exercises to do, including pelvic floor (very important!). I've also got pelvic floor nerve damage on one side (it's at half strength) - and surprise, surprise, that side is my bad side pain-wise too. Oh and I love my body pillow (actually more than my DH at present - he's very jealous ). Apart from that, desperately hoping i can manage this for another 3 months... atm my best treatment is my mum visiting from interstate!

Toddler-specific issues: I'm about to move my toddler into a bed (cot is too hard atm), minimise car trips with him, no lifting for cuddles (he snuggles my bump anyway), changing nappies - both floor and change table are difficult (too high OR too low) but am going to try the sofa. Toys - I'm going to start sweeping them up. Snacks at a kiddie table & chairs rather than in the high-chair. Dressing him - try to plan ahead so I'm not bending over to add extra layers before we go out (bending over to do zippers up is painful!)... maybe more hoodies/simple clothes.

Sending big to everyone else suffering this also, and thanks for the wisdom from those who have suffered it before.
