Prince Louis, who is just three months old, behaved extremely well during his baptism on Monday in London. The little Royal slept through most of the ceremony and even the arrival of numerous photographers in front of the church did not seem to bother him. In a conversation with the Archbishop conducting the service, Duchess Catherine (36) revealed several interesting facts about Louis's personality, according to Hello magazine.

Duchess Catherine: Louis is a peaceful child

Catherine told Bishop Justin Welby (62) that her youngest son Louis was a peaceful and relaxed baby. "I hope it stays that way," she added with a smile. Louis's older siblings, Prince George (4) and Princess Charlotte (3), are both extremely lively and curious.

Prince Louis wore a traditional christening robe, which was the same one worn by Prince William and Prince Harry (33) at their christenings. The crowd were also delighted to see both his siblings, Prince George and Princess Charlotte, looking adorable in their outfits.
