Iris Gill doesn't just like CVS Pharmacy, it's her passion.
The US pharmacy chain holds such a dear place in her heart that when the time came to celebrate her fourth birthday, the theme was a no brainer: CVS.
"This girl's love for CVS is pure and true — so loyal that I recently asked Iris where she'd rather go — CVS or Disney World. Her response? CVS and Disney World. So when your kid puts CVS on the same level as Disney World, you embrace it," mum, Sarah Fortune Gill from Arkansas wrote on her blog.
However strange the request, Sarah says she loves how simple it is to make her daughter happy.
"One day it won't be so simple to make her happy," she writes. "So for now I take her to CVS when we have a few extra minutes to spare and try my best to make her birthday party special, as tricky as it may be (after all, there are no Pinterest boards for this, folks)."
Speaking to NY Daily News, Sarah said: "I knew she loved CVS, but I thought she would change her mind."
"When I realised she was serious, I just rolled with it and tried to get creative."
Iris' love for the chain started almost two years ago when the construction of a new store began near their home.
"The site happens to be directly on our path to Iris' school, so we drive past the location at least twice a day," Sarah wrote.
"Being that she was only three when it opened, she watched the progress of the structure being built for nearly half of her life, so naturally it was a big deal when the store finally opened."
When Sarah told the store about their birthday plans, they sent snacks, supplies and branded water bottles for guests.
Making her day, the store changed their sign to read "Happy Birthday Iris".

As for Iris' obsession, Sarah doesn't think it will go away any time soon.
"As long as CVS has snacks, Iris will love CVS!"
