What age is a good age to put a child in daycare?


I’m a FTM, currently not working and plan on staying home with baby full time for at least the first year. I, however, know it’s extremely important for toddlers to develop social skills early on so I definitely want to place her in some sort of half-day, 3 days a week, part time day care when she gets a bit older. I was just wondering what you ladies think is a good age for that?
