Fisher-Price Happy Days diapers were discontinued in January of 2016.
Fisher-Price Happy Days offers very little beyond the run-of-the-mill for their diapers. The performance overall was just a baby's hair above mediocre, but it carries a price tag we feel implies better. Happy Days had around average scores for all metrics, with a 4 and 5 for leaks and absorption respectfully. It scored below average for the remaining metrics, offering adequate but dull results. When compared to the other diapers we tested, it failed to score as high as some with lower prices. In short, our testing indicates that if you want to be happy, you want to buy a cheaper diaper that scored better.
