She has been capable of doing so for a good couple of months. She walks down mostly, but sometimes goes down on her belly feet first. She has walked up and down stairs hundreds of times without any problem. The only reason I ask, is she fell down them this morning and I am feeling a bit guilty.
I usually watch her doing so, but this morning was one of those occassions where I turned my back for 5 seconds and there she goes! She cried, but calmed down pretty quickly and has no bruises, cuts or broken limbs! (Also no sleepy behaviour, blood in the ears or vomiting!)
