Norwegian news hasn't been reporting much about this issue in particular. I found one (barnehage.no), translated through Google:
«Denmark will introduce a compulsory kindergarten for one-year-olds from vulnerable housing areas
Denmark's government will introduce a free, but mandatory kindergarten for families from vulnerable residential areas, in the fight against gettos and parallel communities.
In the early 1980s, one percent of Denmark's population was non-western immigrants, today the proportion is eight percent, Berlingske writes.
In the edition "One Denmark without Parallel Society - No Ghettos in 2030", the Danish government has set up a list of 22 points in the fight against parallel communities.
Trekker barnetrygd
Politicians want to give imprisonment to parents who send their children abroad and take child benefits (an amount of money parents receive each quarter from the government until the child reaches the age of 18 with the intention of encouraging having children) from parents if their children go to school.
In addition, they will make it compulsory for parents from children in vulnerable residential areas to have their children in kindergarten for at least 30 hours a week from the age of one year.
"Required compulsory daycare is required for a minimum of 30 hours a week for children living in an exposed residential area, from the child's age to 1 year, if the child is not already admitted to a daycare," the government said.
According to the Radio of Denmark, child care facilities must be made free of charge. However, if the parents do not make use of it, the municipality must withdraw child benefit. (So they are not losing all welfare benefits they might receive, only the specific "child benefit".)
Max 30 percent
If the government gets the way it wants, the single kindergarten can, when taking new children, take up 30 percent of residential areas that have been on the gettolist for the past three years, reports Denmark's Radio.
Private kindergartens that over a year occupy more than 30 percent children from these residential areas may lose their approval.
The government writes in its outline that, with the measures, it wishes to ensure that all children in the ghetto areas and vulnerable homes have a good childhood and age-impaired language, and to grow early with values such as gender equality, community, participation and co-responsibility.
The bourgeois government, which consists of "the Left" (A liberal (centre right in Danish politics) party (and also sister party to the Democratic party in the US), the Conservative and the Liberal Alliance, needs support from the Social Democrats to adopt the proposals. The Danish People's Party has so far taken a positive view of the proposals, NRK writes.»
