Moving to a new home is a big adventure, but it can also bring big feelings - excitement, sadness, worry, and curiosity all at once. As parents, we want to validate all emotions, help our children adjust, and make the transition as smooth as possible, but finding the right words to comfort and reassure them can be tricky. That’s where Molly the Moving Mermaid comes in!
This real letter, delivered straight to your child’s post box, has been written by an Early Childhood Educator in consultation with a psychologist to provide a gentle, age-appropriate way to navigate the emotions of moving. Through the heartfelt undersea story of her own big move to a new cave, Molly helps children understand that it’s okay to feel wobbly, home is more than just a place, and new adventures are waiting to be discovered. This letter helps children process their feelings while easing the transition and creating excitement for their new home.

Everything about this was perfect. The timing, the words, the sticker, the colouring pagess she called it her 'moving day treasure.'
This letter had a bigger impact than any of our chats about moving. The mermaid angle made it feel fun and magical plus the sticker helped distract from the chaos!
my daughter lit up when she opened the letter. She asked me to write back to Molly. I think she felt so special being acknowledged in such a big transition.
We read it before bed every night for a week. He was so reassured. The artwork and wording were so thoughtful.
It's such a clever way to help kids process a move. She stuck the sticker on her toy box and carried the letter around for days.
