We tried to use this several times with my daughter (now 5 months old)and she screamed each time. I kept thinking that maybe she was too little, but the carrier just never held her properly. She always seemed to be too low in the carrier and she would want to chew on the straps. I thought that she just may not like carriers, but I bought the Bjorn and she abosolutely loves it! Now that we have used both, there are some serious differences in the way the baby is held and this carrier just does not get it done - at least for us. Also - the difference in the back pressure is unreal...this one really did hurt my back and she is only 14.4 lbs.
