The source says,

“Rob couldn’t be happier,”

He recently posted a picture with the caption reading “My babies so pretty ???”

Apparently Kim is the most involved sister in all the pre-baby planning but mom Kris Jenner is slowly coming around too and offering lots of baby advice.

“Kris has been giving him baby advice. They get excited talking about the baby.”

Super exciting.
