When I was stroller shopping, it was very important for me to find a stroller with a bassinet option. In general, I like to have my baby in the infant car seat for as little time as possible, so this provided a good (but pricey) alternative for me for about the first month of her life. We also had a summer baby, so the idea of having the baby in the infant car seat during a hot, Virginia summer was really unappealing to me.
Some ways I found the bassinet useful:
It was really useful when my husband and I would have dinner on the deck and she could sleep outside in her bassinet. We also used it when we went to the pool and she could lay in the shade for a little bit without getting overheated. We actually used this as her primary bassinet for sleeping at night for the first month of her life. It is very well made and the bed of the bassinet is removable and washable which is essential! It is also extremely easy to snap on to the stroller or take off to use on its own.
Some ways I found the bassinet limiting:
Surprisingly, we did not use the bassinet very much for walks (which was our primary reason for purchasing it). We found that when our daughter was very young (1-3 wks old) she flopped around in it and seemed to feel every bump in the road, as there's no way to secure the infant in the bassinet. By the time she was a month old or so and able to handle the bumpiness a bit better, she was almost outgrowing it. Our daughter was 9 lbs. at birth, so if you had a smaller baby it would probably last longer. For us, we found that using a soft carrier (like a Moby or an Ergo) was the best way to go for a newborn.
All in all, I have nothing but good things to say about the Versa and Baby Jogger. I think the reversible seat is worth every extra penny (when compared to the City Mini). Baby Jogger does not recommend putting an infant in the Versa seat until 6 mos, but I started putting my daughter in it when she was a little over 1 month in the most reclined position, and she has been absolutely fine (granted she is a big baby). In retrospect, for a second child (especially if the child is born in fall or winter), I might forgo the bassinet and just get the infant car seat adapter and use it sparingly.
