Has anyone of you used the pseat carrier for babies? Are there any different from normal baby carriers (ergo carrier)?

Hi Andrea, are you referring to hipseat carrier like i-angel? If yes, I have used for my no.2 when he was between 10 months to 1.5 years old. I like it because it can support baby's weight in natural sitting position and distribute the baby's weight to my hip evenly. I feel less painful on my back and shoulders compared to no.1 time (I used Beco Gemini). After he is 1.5 years old, as his legs are growing longer, I realized the hipseat carrier is not able to support the legs and dangling. Thus, I invested in TULA toddler version where baby's legs are very well supported.
