Kids in same room . Boy2,girl 3 in same bed room a problem?

At that age I do not believe it is an issue. Our son had twins, boy and girl, and they slept in the same room until they were 4-5.

Many families can't afford to rent a place large enough for every kid to have their own room. Unless you live in the projects on Section 8 housing... there are no restrictions.

Generally such laws refer to public housing or they are very localized so you would have to check with your local building dept. Also such rules are usually only an issue if someone complains. But I can't see an issue with it at those ages.

In General, there are not laws, there are rules and guidelines, if you want to live in Government housing (low income) or get section 8 housing, they will have rules.

If for some reason you are being investigated by CPS, they will have requirements and rules they want followed.

Normally there is no one to ask this question and at least in America, there is no government agency coming in and inspecting your home. ** this is not true everywhere.
