I got my birth ball from Argos for £4.99 (put "gym ball" in the search box), and it's fine but a lot smaller than the one we use at yoga (think it's 65cm). Still fine for leaning on but it's hard to get my knees below my hips when I sit on it, without stretching my legs out completely! Not sure we'd have room for a bigger one though.
Annie, thanks for all the tips. Your day sounds lovely, enjoy it! I want to keep it really informal, I'd happily have no speeches etc, but DP isn't keen! Maybe I should make him plan it all. Having LO to puke on my dress will definitely make the day less formal anyway. Just hope I can wean him off bf by then.
Kiteflying - glad the Royal Free was lovely and you've finally seen a mw!! Love the garlic plan. I've been doing lots of hip rolling on my gym ball and I'm feeling less achy. I'm seeing a chiropractor tomorrow, will wait to see what she can do before I book an osteopath.
Bananabump, so glad the consultant was nicer than the sonographer, silly moo.
TT - love the dresses and the bump!
