When you have the exact birth details, your child's poster will have 7 pieces of content.
From their Astrology Natal Chart:
Rising Sign - How you look to others looking at you.
Sun Sign - How you see yourself and who you're learning to be.
Moon Sign - Your emotional personality and how you feel about life.
Jupiter Sign - Your super skills, the things that will expand you and bring you abundance.
North Node Sign - Your destiny or life path . . . the direction you are here to go in.
From their Human Design Bodygraph:
Energy Type - The energy you were designed to bring to the world and how you best interact with the world.
Profile - Your life 'style' or character. The first number represents the personality you identify with and the second represents how others see you.
When you only have the birth date, the poster includes 6 pieces of content (only one Human Design piece and 5 Astrology pieces) and less of a 'life purpose' feel.
