How many??

Hello ladies, first time mom here.

I am just shy of 7 weeks pregnant... but I have let Pinterest take over my life, haha. I spend a good chunk of my day planning our nursery and potential registry. So I know it's a bit early to be worrying about this stuff, but I just can't help myself!

How many nursing bras do you think are necessary? I plan on breastfeeding, but I hear it is one of the most difficult things I will ever do. So should I just get two to start with? And then if I decide that's the route we're taking buy a couple more?

I hear boppy pillows are a lifesaver. How many covers do you suggest I buy for it? (Etsy has SO many cute ones!)

And last but not least, how many receiving blankets and swaddles would you suggest?

Thank you in advance for your help/advice!
