My son Koi is 9 months and the only time he will fuss is if he is hungry or if his teeth are hurting other than that hes always super happy!
He loves playing with his toys and loves mrs rachel every once in a while. He will eat just about anything you feed him and he loves talking mainly likes saying baba or mama.

Just need someone to be able to watch him for a little bit during the day will never need him to be watched over night
