My LO is 3 weeks old weighing 3.7kg. I am looking for affordable carrier that can be used from 1st month to at least 1 years old. Dont really like infant insert as my LO perspire a lot. Kindly recommend any carrier that is suitable for newborns without infant insert if possible. I am actually incline to buy ergo baby 360 cool air mesh carrier but my LO is 3.7kg and according to ergobaby website, they require LO to be at least 4 months old in order to remove the infant insert. Heard KTan carrier is good for newborn but not much reviews.
