Found the stairs

My niece and daughter are 5 months apart, and are quite the team. Always getting into things. We found them both on the stairs, where Elle learned for the first time how to go up, so once daddy got home we had to show him, and of course get it on film. While uploading the video's, Elle and her cousin, thought they would type up a message of their own: 8666666666666666/8+2/8+**++++++++++++++++++++++++++++++++.9+0...........++++++++++++++00093 ................................63.020. +0-+ 20000000000000005201.2.+* 4+
