Prince George And Princess Charlotte Couldn't Be Happier About The Royal Baby

Prince George and Princess Charlotte are not feeling any sibling rivalry when it comes to their new baby brother Louis. The royal children were over the moon about the birth of the little prince!

Kate Middleton gave birth on April 23rd, and photos of George, 4, and Charlotte, 3, showed that they were all smiles when going to meet Louis for the first time. A source revealed to OK! that they were "bubbling over with glee!"

"Now that the baby is here," the insider continued, "George and Charlotte are totally besotted with him."

The kiddos spend 25 minutes with their little brother in the hospital in London before their nanny, Maria Borrallo, took them home, according to reports.

"The children couldn't sleep a wink after Kate left for the hospital early Monday morning," the source dished. After their time in the hospital with Louis, the insider said "they could not wait to welcome him home with drawing and cards."

Now Charlotte and George are getting hands-on experience with their kid bother. "Kate allowed Charlotte to hold the baby first, and she was speechless with wonder," the insider said. "Then George bent down to softly kiss his brother's head. It was a darling moment."

And Kate and Prince William aren't done expanding their family just yet. They plan on having four children, according to the source. "William would love to add one more baby to the mix," they said. "Plus, it's likely only a matter of time before they start hoping for another little girl!"
