I ask my wife which one is her favorite sometimes....We have 4 kids, 7 and 6 year old girls, 5 and 18 month boys....The seven year old is my favorite, she helps clean, does well in school, and she listens(Dont have to tell twice often) when i tell her important things about life....Still hella wild at times but she's just a kid.....The other 2 the 5 and 6 year olds, dont do well in school, dont listen well, i have to tell them the same shit more than twice....But they are fun and do different things well...And the 18 months is climbing all over the house, putting his hands in the fish tank....is starting to say "mine" all the time jumps and hangs off shit, climbs out of the play pen.....I cant take my eyes off him....I love them all, but the 7 year old is extremley sharp...
