Not sure. Harlea hasn't encountered them yet unless you want to count the little 2 step stairs she had to help her up on the couch before she could jump up. lol
Hahaha. Bless Izzy's little heart. The first time she tried she got to about stair seven at my parents (she was about 3 months and they are wooden stairs) and then slid down to the bottom on her belly with her legs splayed out!
Izzy was so scared of them for the next few visits, but she's mastered them now.
Does great with them! We live on the 3rd floor - at first he was too scared, now he just full on beast modes down and up them. If we are busy doing stuff and he wants to play he knocks the ball down the stairs and runs down gets it and does it all over again
My boys go up and down the stairs as many times a day as I do..they do not like to be alone..sometime Romeo runs down so fast he looks like he's going to roll but it hasn't happened yet
