I had a sling with my daughter but that was 9 years ago and to be honest I used it one time and put it away for good. I just didn't feel like she was secure in there, like she was going to slip out at anu minute. plus it always looked like it was suffocating her. I forgot what brand it was but with my son (5yrs ago) I used the carrier you buckled around your torso, where he sat in front against my chest. I liked that one better but it was ugly lol
