Ahem....
Please let me introduce myself!
Used to work for Bravissimo as a bra fitter, now work for Mothercare & do most of the fittings in our store. Including nursing mothers, mums to be, oh, and the occasional Grandma to be whose never had a proper fitting!
Best time to get measured for a nursing bra is 36 weeks +
Basically the later the better as your rib cage can expand still in the last few weeks of pregnancy.
Some women even wait until after having the baby when their milk has come in and they are happy feeding rather than spending on something they may not use and which is an estimated size.
- Measure in inches the circumference under your boobs.
- Your bra should fit TIGHTLY around and do up on the LOOSEST notch.
If you find it uncomfortable then go up a back size. But, generally, after the first few weeks of having the baby your rib cage measurement will decrease. So its best to go as tight as possible and wear a bra extender (available from NCT or good habadashery stores for approx £2) until your rib cage goes down. Else, you will end up with a bra which is too big for you in the back and which will ride up in the back and then not offer the correct support which you need.
- The Cup.
There is no proper way of measuring this yourself without trying bras on. Even in mothercare the same size in different bras varies greatly. Basically you want a bra which is baggy in the cup on you. I normally advise just going up one cup size unless you've had one or more pregnancies already where you've increased massively (like myself who started off a 32F before DS, then went up to a 34K when feeding!! - dread to think what size I'll be this time round, already wearing a 36H!)
You should be able to get your whole hand into the cup at this point. Its got to accommodate for engorgement & also for breast pads.
Hope this helps.
Any questions - please ask away. Or - if you live near me I'm 35 weeks gone too and more than happy to help you out!
