Each has its advantages and disadvantages. We are hearing more these days about undiagnosed brain injuries, with symptoms too subtle for doctors to detect, but very real to families. And that comes to mind whenever someone asks us about babies and biking. Trailers Trailers are perhaps the safest way to take a very young child along. They are lower to the ground, so when you crash the baby will fall a shorter distance, even when you turn the trailer over.
Most parents have no idea how rough a ride it can be in a trailer.
Trailer arrangements can be better if you wedge the child's head in on both sides so it cannot bobble around. But seated upright in a trailer the baby also needs a pillow behind them to provide clearance for their helmet in the back. Without the pillow their head is forced down by the back of the helmet. Even if you use a child carrier that keeps the baby perfectly stable, the child will be subjected to a rough, rough ride. Trailers with low-mounted hitches are generally more stable, but the wheels can snag on obstacles as you pass, and many trailers can turn over with surprising ease if one wheel rides up on something like a curb, or if you just have to take a turn too sharply.
