Kids are allowed into the casinos, but they are not supposed to linger to long in the casino, for instance if your were gambling and they were close to youthey will ask you to leave, but some of the casino off of the strip have daycares connected to them or real close to the casino. I live in Las Vegas and I know 2 off of the top of my head that have daycares connected and they are the boulder station and sunset station. I hope this helps BTW they also have movie theatres or arcades for older kids (in the cAsino)
