We used ours until DS was about 3 months old, but because he was born in March and it was still pretty warm, he used to get cooked in there as it was pretty deep and not much breeze went through it. The main reason I bought it was because my pram (Baby Jogger City Elite) was not suitable for a newborn (I read a review on the pram before I bought it) and I wanted bub to face me for a while. I didn't use it for going out much as DS was a big baby so he started to feel cramped up in there pretty quickly.
