Princess Charlotte and Prince George are preparing to welcome their new sibling with Kate Middleton and Prince William’s help

Princess Charlotte and Prince George are just months away from meeting their new sibling when Kate Middleton gives birth in April, however it seems that Princess Charlotte is particularly excited about becoming a big sister – thanks to her parents' careful preparation.

Us Weekly recently reported that two year old Princess Charlotte is very much 'looking forward' to the arrival of her new baby brother or sister, after a source revealed to the magazine that Kate and Prince William have been helping to involve their two children in the excitement around the birth of the new baby.

'William and Kate like to keep Charlotte involved and part of the excitement around having a new sibling,' the magazine’s source revealed.

Kate and Prince William reportedly used the same tactic in 2015 with Prince George before Princess Charlotte was born, to help prepare him to transition from being an only child to being a big brother.

The young Princess is apparently 'very aware she's going to have a new baby brother or sister' and she's even been practising her big sister skills with the toys and dolls she has at home in Kensington Palace.

'She is probably expecting the new brother or sister will be the same game — but in real life' the source revealed about Princess Charlotte.

The sweet revelation about Princess Charlotte’s preparations to become a big sister come after the Queen revealed last month that despite being two years younger than Prince George, the little royal still likes to boss her big brother around.

'The Queen was implying that Charlotte keeps an eye out for George' revealed the father of a young girl who chatted to the Queen during an official engagement at the Monarch’s Norfolk estate Sandringham.

So it seems young Princess Charlotte is more than ready to become a big sister to her and Prince George’s new sibling!
