You can hire them pretty early. It depends on the demand in your area. You’ll pay the same either way because a doula really does their work in the 3rd trimester.
I have a doula because I’m going to a hospital and having my doctor or another in the practice deliver the baby.
If you want someone to provide prenatal care and also deliver the baby, you want a midwife. Midwifes are often nurses as well. Medical training.
