What I like is a practice that also carry with physiological scarf, but it is faster to implement. Baby frog position is comfortably placed. For the carrier, no back pain or on the shoulders because the straps are padded and can not position error !!
That will make 3 years that I have and I still have my first 3 years past that weighs 15 kg for small tiredness. IN contrast, my second 13 months will very often still in ballads and I still wear a little on his stomach when he's tired, otherwise it prefried back because he can see many things !!!
However, I am an amateur scarves but sometimes too lazy to do the knots, I will not deny my benefits of carrying babies, hence the manduca !!!
and my husband also adopted while he never wanted to wear the scarf. With the second stroller was stored in the closet !!!!
