sounds normal, think yourself lucky thats all they do LOL LOL LOL
today my 8 mnth old boy leapt at a wall and got about 2/3 of the way up (we have quite high ceilings) just coz there was a spot on light shining through the blinds , other days he goes about leaping and rearragning my photos knocking them all squint and he not only steals socks but also small ornaments and anything else he can carry and hides his contraban behind the sofa, he throws half filled hot water bottles around like a dog would and also tears through the house with my husbands trainer banging behind him (my husband got size 12 feel so its a bloomin big trainer) LOL
