I purchased Boba Bliss for my baby when he was smaller and loved it.I decided to purchase their infant to toddler carrier because of the back support as the other one was causing back pain since my baby is on the bigger side for his age.I was worried because in the photo the carrier looks like a dark grey but it is actually the pretty light grey color I liked as the Bliss carrier.It was easy to wear and baby fit just right in it.It provides back support and I like that I can cross the straps for extra back support.I love that it is hip healthy and it will grow with my baby.Price was a little on the pricey side but quality seems worth it.There was a weird smell that also came on my previous carrier but with washing it it eventually went away.Edit: my baby is not 20lbs and almost 9 months and we use this daily sometimes multiple times a day, I started using him on my back when I am cleaning around the house and it is comfortable and he loves being carried, he falls asleep on this carrier almost everytime. I will be sad when he outgrows it, thank you Boba.
