RUFF Logo + First Instagram/Facebook Post

RUFF is a psychology-based child behavior support brand. We need a simple, modern logo and a first introduction post for Instagram/Facebook that feel clean, clinical, warm, and trustworthy.

The brand should feel like:
child psychology
behavior support
development
guidance
support for growing minds

Please avoid:
dog logos
pet branding
cartoon animals
toy-style designs
bright childish colors

Preferred colors:
dark navy
soft sage green
muted green-gray
light blue-gray
warm peach
soft beige/cream

Deliverables:
1 simple RUFF logo
1 first Instagram/Facebook introduction post using the logo
Color palette
Font suggestions if possible

The logo and post should match my website style and work well across:
website
social media
business card
app icon
pitch deck

I uploaded inspiration images. Please keep the style soft, modern, professional, and trustworthy.
