How do you help your SO

How do you help your SO get over being worried/embarrassed about breastfeeding? We spent 4 days in the hospital, where the doctors and nurses are used to seeing babies on the breast, and SO was obsessed with either grabbing me blankets to cover or pulling the curtains so there wasn’t even a sliver of ability to see in while I nursed.

After we went home, we stopped to visit his sister (who still breastfeeds her 2 year old) and I went to breastfeed. I do the 2-shirt method so it’s really modest and you can’t see anything, and he tossed me a receiving blanket to cover with. I’m like...dude, she’s breastfed her toddler without a cover in front of me, I don’t need to cover when his head already covers everything.

At first, I thought he was just being helpful when he did stuff like that, now I’m thinking he’s embarrassed. Will he get over it in time (LO is 10 weeks) or am I going to have to tell him to chill out ?
