From the Montreal Gazette on the NDP daycare funding announcement:

Layton also said daycare would offer support for children at key moments and serve as a preventive measure against violence.

"Good child care (and) afterschool programs give our children the help that they need, identify the problems that they face, so that they can make choices that don't lead them down the wrong path, for example violence in the school yard," Layton said.

• More time spent in daycare centres leads to more children having higher levels of behaviour problems - including "cruelty". The extremely rigorous child care study by the NICHD in the US found that this negative behaviour continues at least until grade 6 and happens regardless of the quality of the care.
  
  
• A peer reviewed study of Quebec daycare (by economists Drs. Milligan, Baker, and Gruber) using Statistics Canada data found significantly more child behavioural problems reported in Quebec compared to other provinces after the $5-a-day program started.
  
  
• After over 30 years of near-universal institutional child care in Sweden, domestic violence against women is increasing, contrary to the goal of greater "gender equity" according to a leading Swedish feminist (see CBC link)
  
  
• Peer reviewed research finds children's stress (cortisol) levels increase with time in daycare centre.
  
  
• In recent years France has repeatedly erupted in mass rioting and youth violence despite years of massive daycare/preschool programming.
