For me I love to play:

The Bratty Mischievous “Big Boy”: This persona though in diapers loves to play video games (probably not suitable for a little), loves to get themself into trouble, and has a love/hate relationship with the word “no”. This persona is supposed to be in potty training but is always going to say no when asked if they OBVIOUSLY have to go. Is very pouty and whiny and can and will try to get out of trouble using puppy eyes, and or whining your ears off. Hates nap and bedtime! But falls asleep quickly. Like to knock blocks down in fact they’ll do anything for a “Don’t do that, that’s Naughty” reaction. Can be hyper at times. Doesn’t like to use words all the time. Not to say it’s all this persona is all Mischievous. They can be cuddly, calm and clingy.

Some days I’ll be a bit more calm and quiet than others but I don’t really count that as it’s own persona that’s more as IRL me.
