Can any bra interventionists advise on how much breasts are likely to change post-birth and when is best to order nursing bras? I'll need a larger size so am looking at £40+ per bra for flexi-wired ones from Bravissimo and keen not to get it wrong! No store where I live so will have to order online. I'm wondering whether it's worth ordering pre-birth or whether it's actually better just to wait till after baby arrives and do a next-day delivery at that point. But I've also heard that breasts can fluctuate a lot in the first few days - and how much do they actually settle down afterwards...? Is it inevitable to end up buying and wearing more than one size of nursing bra?
