Is confinement lady important?

I do not have a confinement lady. My mum came for a few hrs each day (6-7hrs) to bring me my food and help take care of my little one . I feel the initial part is the most important when taking care of your LO. I see a lot of my friends having problems n babies get cranky after CL left. And they don't understand their babies even after 1 Mth
