There is no evidence to suggest that Prince William and Kate Middleton sleep in separate beds.
The royal couple has been married since April 2011 and has three children together. While the royal family is known for following certain traditions and customs, there is no formal rule that dictates whether they should sleep in the same bed or not.
It is worth noting, however, that some members of the royal family have historically slept in separate bedrooms or even separate residences due to the demands of their duties and the need for privacy. For example, Queen Elizabeth II and Prince Philip reportedly sleep in separate bedrooms at Buckingham Palace, although they are known to have a strong and loving relationship.
In general, the sleeping arrangements of members of the royal family are not typically discussed publicly, as they are considered private matters. While there have been rumors and speculation about the sleeping arrangements of Prince William and Kate, these claims are largely unfounded and based on speculation rather than solid evidence.
It is also worth noting that the royal family is known for maintaining a high level of decorum and professionalism in public, and would be unlikely to discuss their personal sleeping arrangements in public. Therefore, it is impossible to say for certain whether Prince William and Kate sleep in separate beds or not, as it is a matter that is likely to remain private.
In conclusion, there is no evidence to suggest that Prince William and Kate Middleton sleep in separate beds. While some members of the royal family have historically slept in separate bedrooms or residences, it is unclear whether this is the case for the Duke and Duchess of Cambridge. As with all matters concerning the royal family’s private lives, the couple’s sleeping arrangements are likely to remain a private matter.
