Figuring I need at least a couple of nursing bras for my hospital bag and first few days home with baby (don't like the idea of receiving visitors braless lol). So should I buy now or wait a bit longer? I'm 33 weeks and don't really feel my boobs have grown too much. I'm actually still wearing same bras but with an extender. So should I buy one size up, two sizes up?                 
                             
        
Re: When to buy maternity bras?
She suggested a few sports bras or a few cheap nursing bras
They were cheap target ones.
Most places I read said you were supposed to wait as long as possible for your true nursing bras BUT when I looked at discussions of people that took that advice many said those bras fit at 36+ weeks only fit for about 2 weeks postpartum when there milk came in and their boobs were huge but once they had gotten nursing established the bras were really to big.
I followed the recommendations on Seraphine dot com and they said 26 weeks was a good time to measure and that you may go up 1 band size and 1-2 cups through the rest of the pregnancy and milk coming in--which sounds like a lot but didn't actually matter much in sizes for me because of nursing bras being sized at small, medium or large.
