I know this is going to sound bad but my husbands kids are driving me insane!! mine is too as well...But their mother don't punish them so we have to be the bad guys all the time cause when they come here they think they can do whatever! I am not having that! I am 35 weeks pregnant and sick of being pregnant and then having them come here running around and screaming! I am so close to losing my shit!! I'll be damned if they will act like this when the baby comes!
