Infant Care Or Helper?

I'm thinking between getting a helper or sending my baby to infant care once she reaches 2 months old. I'm a preschool teacher myself, and there will be days whereby I am not able to pick her up after work. Additionally, my hubby ends work later than me as he works split shift so it is hard for him to pick her up as well. As for helper, there wouldn't be anyone at home, and would be leaving the baby alone at home with the helper. Hence, I am worrying about the cons for hiring a helper.
