You can use a structured carrier now instead of a wrap, but not forward facing yet as they’re still too young. Thebabywearing.ot on Instagram has great info on all things carrying and baby wearing!
I wear my son fowards . He has good head control and usually rest on one side anyways
The wraps you don’t have to tuck in legs … just make sure they are in an M shape so the hips are good. Mine is 13.8lb and moby still works great for us. Also I like when she faves me bc she can bury her face when she wants if it gets too loud or bright.
You can have their legs hang in the moby and any soft stretchy wrap. They don’t have to be tucked in. That being said, the bigger the baby, the less comfortable the soft stretchy wraps are in my opinion. Most front facing carriers aren’t great with leg positions. You don’t want baby’s legs to just dangle down. Once they have head control, I highly recommend a soft structured wrap like an ergo as babies get big.

They usually say if they have good head control you can put forward facing
