Toddler fell off sofa , now stuttering

Toddler fell off sofa , now stuttering Hi , just looking a bit of advice last night my 2 and a half year old fell backwards off the sofa and banged the back of her head on wooden floor , she cried but then was fine, today she’s stuttering really badly , she did stutter a few months back but it disappeared, its now back and worse than what it was, could this be linked to the fall , when she’s playing with her toys she’s speaking clear but whenever she’s having a conversation she’s stuttering
