Hi, actually, using too much of walker may delay your baby's walking independently. Because the babies can get around too easily, their urge to move across the floor is satisfied, and many of them will not undertake the important task of crawling, creeping, scooting, or hitching. This stage is important for developing strength and coordination.
Also sometimes baby walkers get dangerous because they give babies extra speed, extra height, and access to many hazards.
Hope it helps!
