I have tried so far with the baby before because there are still too small to go in the back (reported from only a year and my babies 5 months). Hence the 4 stars and not 5 because I did not test it in its entirety. This baby carrier is really comfortable, no backache after wearing the baby (there are currently 7 kg), plus the opening system to put in place baby is well thought out and very easy to use. The opening from the front greatly facilitates the introduction of the baby. Be sure to read the instructions for use the first time but once understood the system it's very fast and super easy. I already had a BabyBjorn baby carrier as the "original" model I already good but I feel that my babies are increasingly cramped in, while in this one there are many more comfortable as there is more possibility of adjusting the baby's level and "sitting" is wider too. I look forward to try porting on the back.
It is on it remains an investment considering the price, but the quality does BabyBjorn never failed me before.
