I am fully satisfied with this door bb physio who saves my back and respects the physio positions of my baby .. at first it made me marks the hips but after 2 or 3 walks manduca became my body (just like shoes) .. perfect for continue wearing baby and prevent back pain, so far I wore my little elastic sling but now he weighs 8kg + it was not possible for my little back !! Here I would 100% recommend this baby gate that I use every day: very easy to use, friendly and mom and baby is more beautiful !!
