If you want to do the beautiful and easy hike from Lauterbrunnen to Stechelberg, and you keep to the right (western) side of river and valley, yes, there will be a road, but with only little or local traffic. Somewhere there will be signs showing you where to cross the meadows to reach the Trümmelbach falls. From there to Stechelberg the road will be busier, but if you want to hike on you can always cross the meadows again.
Just to let you know: the Trümmelbach falls are inside the mountains, so this might be a bit harder with a baby carriage. The first part up can be done with a small elevator, but there are also stairs, and for a baby it's dark inside, there's a lot of noise, and it's wet.. But spectaculair though!
I'm pretty sure you will enjoy the Lauterbrunnen valley itself, even if you skip the Trümmelbach falls. There's always the Staubbach fall (near Lauterbrunnen) and the Mürrenbach fall (near Stechelberg).
One of my favourite hikes!
I hope you will enjoy the hike!
