I
You look super tiny BF. Have you gotten any idea from your checkup a how small your LO is? C was enormous and never even fit in the NB size stuff. I bought it and had a ton, but it all went unused. I stuffed her in one once just because it was too cute, but we didn't need them.
I had a few newborn sizes & was glad to have something that fit him well for pics.
He was 8 lbs 2 oz & 22".
They only lasted a few weeks, though, so it's definitely not essential.
Did you see Melly's before & after pics of Julian on Facebook?
How big was C, Viking?
