What is an ideal age for a child to start daycare?

Pregnant single mom no friends or family. The plan is to save money and buy everything I need now so that when the baby is born, I’ll have a few months of home time. maybe I can start doing self-employment jobs like delivering groceries for a little until I get my baby into daycare so I can get a full-time job*

What would you say the ideal age is to put a child in daycare ?

Hate this idea but I’ll do research and make sure it’s a safe environment.

Edit; thank you!! 🥺
