When to get measured for feeding bras?

[lilyborderterrier]

This is my 2nd pregnancy and my breast haven't really grown, going from a 34c to a 36 D at 34 weeks, my first pregnancy I was massive up to a DD, but I've only needed to buy a few comfortable pregnancy bras but I do try to plan to breast feed this 2nd one again. When should I go and get measured for new bras? After the baby is born or will my boobs suddenly explode in a few weeks as I get closer to the birth. Annoyingly the closest mothercare I used in 2013 has closed down so I've got to go further afield. ( I hate shopping and buy most things on line)

I bought some bravado silk bras for the late pregnancy/early BF stage, they are amazing. Then got measured once boobs had settled down a bit.

I really really recommend measuring yourself at home using the Boob or Bust calculator, if you search on google for it they have a website, I've been wearing the wrong size for years and am so much more comfortable now. I think they recommend wearing soft crop top style bras for 8-12 weeks after to let your supply settle, and no wires until after the 4 month growth spurt I believe
Measuring myself has changed things massively, and no need to faff about in a changing room with a baby!

In s similar situation only really gone up 1 cup size and back, but I just got some nursing bras from Asda and order next size up( cup size) but also ordered the ones in sizes s,m,l etc and where by the size chart. Collected them at the weekend and really impressed they are so comfy, and I'm not due til September but can't stop wearing them!!!
