Sleeping in just a diaper and T Shirt is the best.
It's the most comfortable outfit to sleep in.
Sometimes I also love to sleep in my footed pajamas like I wore as a real toddler.
But on warm nights and on warm days I prefer to be in just my diaper and shirt or just my diaper.
I slept last night in just my diaper, shirt and socks and it felt so great.
I also lounge around the house and play in the house wearing just my diaper, shirt and socks.
It's a great feeling to wear just a diaper and wearing just a diaper around the house makes me feel more like the toddler I feel like I am.
