My Mommy is in America and She Met Buffalo Bill 2013 on netflix

Jean’s father is always busy at work, so he spends most of his time with his nanny Yvette and neighbour Michelle. His mother is away but nobody talks about her. Luckily Michelle is on hand to read postcards about Mum’s Wild West escapades and, even though they seem far fetched at times, they keep Jean happy. At school, the steel marbles Jean takes from his father’s factory are valuable playground currency but their removal has unexpected consequences. This delightful, bittersweet animated film, based on the best-selling children’s story by Jean Regnaud and Emile Bravo, is a joyous, thought-provoking tale about childhood loss and the need even for adults to hide from the truth at times.
