Need advice from 2nd or 3rd time Mama's !

Je

I need so advice. My breast milk didn't come in with my first born for an entire 5 days. I was devastated to heart the first 2 days of my sons life he was not being fed and lost too much weight.

**Now that I'm having my second child. Is there any way to start producing breast milk before my baby arrives or getting my let down to come in faster as soon as she arrives?

Any advice will help or similar situation as mine to comfort this anxious mama.
