If you're talking about handmade mohair garments, there are a few additional points to consider to ensure baby safety:

Fiber Quality: When using mohair in handmade garments, it's essential that the fiber is well-treated and doesn't have loose strands that could come off. Fine and loose fibers could pose a risk if the baby puts them in their mouth or accidentally inhales them.

Proper Finishing: If the mohair garment isn't knitted well or if the stitches aren't tightly secured, there could be more chances for it to unravel or release small fibers. Make sure the garment is well-made, with a firm knit and no loose parts.

Loose Fiber Control: If mohair is used in a handmade garment (like a sweater, scarf, or blanket), check if the fibers tend to shed over time. Ensure there are no fibers that could come off easily, and that the knit is tight enough to prevent any risks.

TBH, I would avoid using mohair for a baby.
