Hi stellarvu,
Nice store, clean and simple. One suggestion though, you might consider including photos of the back view for the clothing products you are selling, especially the pants :)
With regards to Aptamil, I visited their UK site and this is what I read in their corporate inquires link
For information about our products and services please email our Careline team.
Aptamil UK do not provide services or export product to countries outside of the UK. If you have an overseas enquiry please contact the appropriate Danone office.
I visited www.danone.com and was unable to find a link that pointed to wholesale distribution. I will try to take a another look and see if I can find one.
In the mean time here's a post also looking for Milk formula, you might want to have a read -
