A timeless way to document the first year
Milestone sessions are designed to capture your baby’s personality and sweet details in a clean, classic style that never feels trendy or overly posed. Sessions are simple, baby-led, and styled to keep the focus on your little one.
Perfect for the sweetest stages
These sessions are most popular at 3–4 months (smiles), 6–9 months (sitting), and 12 months (first birthday), but can be scheduled at any age. If you’re not sure what milestone is best, I can recommend the perfect timing based on your baby’s stage.
Studio or outdoors
Milestone portraits are available in my O’Fallon, MO studio or outdoors at local parks in the St. Louis area, depending on the look you love most. Studio sessions are especially popular for a clean, timeless look with controlled weather and timing.
The first year truly goes by in the blink of an eye.
Sitter Sessions
(6–9 Months)
Sitter sessions are best scheduled once your baby can sit independently. This stage is one of the most popular milestones because babies are expressive, happy, and full of personality. Sessions are simple and timeless, with styling that keeps the focus on your baby. If your baby is sitting independently, this is the perfect time to schedule a milestone session.
First Birthday & Cake Smash Portraits
First birthday portraits are a meaningful way to celebrate turning one. These sessions are designed to feel classic and natural, capturing your baby’s personality and connection with family. First birthday portraits can be simple and classic or styled with a theme. Cake smash sessions include a simple cake, and custom balloon garlands are available as an optional add-on to truly personalize your theme.
