I have found that a great deal of French media is available through the Amazon.co.uk at really competitive prices.
Here's the pick of the things I would recommend.
This page is a work in progress and I expect it will grow organically over time.

Books
A great little online store selling bilingual books in various language pairs is La Passion du Papier.
Bonne Nuit
Martin bébé lutin
Le vilain petit canard - part of a wonderful series of classic tales that have been presented in the perfect way for little hands. Good stiff pages which are easily manipulated, short paragraphs and wonderful textures to touch. Each story also has a lovely pop up page (this can be rather delicate but is always a huge hit with Poppette when she she's the creation jump out from the pages).
50 Histoires à lire en turbulette - a lovely compilation of short stories and rhymes with beautiful illustrations.
Activity Books
365 activités avec mon bébé - fantastic book created by Gymboree with 365 suggestions as to how to stimulate your baby's senses. Also an absolute goldmine of baby related vocab.

DVD's
Trotro L'intégrale - Trotro is a little donkey and is as cute as they come. His stories relate to typical toddler situations and are infused with humour. Dealing with playing, sulking, learning, sharing (or not), laughing, crying etc. Each episode lasts around 3.5 minutes so they are a great length for young ones.
English DVDs with French Language Options
Another non-native Maman who is a friend of mine has done an awful lot of research into which English DVDs can be bought with a French language option (she has also helpfully noted the other available language options). These are often far cheaper to buy (through Amazon.co.uk) than their French counterparts (through Amazon.fr) even before you discount the cost of international postage. Et voilà la liste so far....

CD's
Babies first steps in french - This is simply fantastic. The CD, which lasts for approximately an hour, is a combination of rhymes (some sung and some spoken) and spoken phrases entirely in French spoken by French natives. The CD is accompanied by a lyric sheet and a booklet explaining early language aquisition in babies. The idea is that if an infant is exposed to the sounds of a second language before it's first birthday it will have the ability to pronounce the sounds of that language without an accent.
80 Comptines à mimer et jeux de doigts - 80 short and classic French rhymes with a small booklet containing the words and hand actions that go with each.
Les Contemimes - brilliant! Completely original rhymes set to really upbeat music. Great for introducing new vocab to young children. The CD comes with a lyric book.
Mon ABCD des Comptines - another great book/ CD combo.
Coco et les Bulles de Savon - Coco is a little mischevious monkey who always gets himself into scrapes. This book is part of a collection. The accompanying CD tells the same story and is set to music which introduces certain everyday sounds to children.
