Huh. My stroller had a facing-me option for young babies--the carseat capsule just slotted in. Rowan hated walks in the stroller (she hated being worn too, so the stroller it was if we had to go out--or more likely, me pushing the stroller and holding the baby!). As soon as she was big enough to go in the stroller facing away from me (no capsule, wedged in with blankets, sitting up and viewing the world), she loved it! I think it was partly getting to see where she was going, and partly the more comfortable incline--she always hated the semi-reclining carseat position and preferred to sit up straight.
I do talk to her a lot though, even though she's facing away from me. I get a lot of odd looks; people tend to assume I'm just muttering crazily to myself.
How much time did the babies in the study spend in the strollers, I have to wonder?? Surely a parent who spends most of the day interacting with a baby, then puts it in a stroller for a 20-minute walk, isn't risking its emotional development (even if she does basically ignore it for the whole 20 minutes). Unless babies are spending several hours a day in the strollers, or the parents aren't interacting sufficiently with them in non-stroller hours, it seems fishy to me that their wee psyches would be as devastated as the article claimed.
