Definitely recommend Momcozy x
Momcozy isn't suitable until they're 3 months old. I would go to a sling library and try some on, it entirely depends on where you carry more weight and what you find more comfortable. What suits one person will be really uncomfortable for another!
I have the Ergobaby Baby Carrier Omni 360 which is great for plus size and from newborn.
I got the mom cozy one. I'm roughly a 16/18 42FF chest and I have a decent amount of extra strap for tightening it up or having it loose. I tried it on at about 8 months pregnant (to check size) and it fitted then as well.
Yes try momcozy carrier
