You might have to get one of those stretchable momcozy wraps. That’s what i plan to do. So much easier to handle than a baby carrier.
I too am considered obese and the boba wrap has a crap ton of fabric and worked for me. I’m 5’10” and over 300lbs forgot to add that in to my first message
WildBird has sizes for their carriers. I think they have one that goes up to 4X
Just from my experience shopping online myself there are lots of brands that sell larger sizes with more fabric. I've found lots of communities online (reddit, fb groups) with discussions and recs. 🩷
You can try the Hope and Plum, Kinderpack or Tula for plus aize friendly brands !
I would google plus size baby carriers and it should give you lots of options. Just look at reviews and hopefully you can find one you really like.
Have you tried a boba wrap?
