Well I knew my first pregnancy was also my last.
My must-haves were a hypnobirthing course, and a doula since I was consultant-led due to having had a full-thickness myomectomy 7 yrs previously ([sigh] still treated like a VBAC after all that time). If we'd have been able to afford it I would have an IM for a homebirth.
Must-haves I've discovered in the last 3 years since conceiving are:
A breastflow bottle to try for ebm (LO was a bottle-refuser but it's not the end of the world)
A bamboo stretchy wrap sling (having discovered how soft bamboo fabric is)
A Melkaj sling (they look lovely)
A giraffe print Connecta
Umm... I think slings are the only things that matter really
I went for too much practicality this time (or what I could get second hand) so I'd go for prettiness if I had another chance.
