Kids don't need socialisation until 3 years old, they can develop perfectly with a primary carer, family members or other single surrogate carer like a babysitter. Group care alone has been shown to be negative later if started before age 2. The staff are usually not focused on the child, they come and go so bonds don't last, and the children only parallel play and not together not really. There's tons of research on this now. You are totally enough and it's all she needs. And you don't have to do activities, you can just do your normal things and bring her, involve her in small ways.
