"Mommy U shut up"

oh my dear son. the past few days all i hear out his mouth is NO and SHUT UP. dear son u are 3 yrs old and you should not be saying these things to your mom. better yet you shouldnt say it at all. arianna is starting to talk also so she says NO all the time. arggggg kids sometimes i just want them to not ever talk. other then that we have been doing ok just living life.
