I, personally, don't believe you need to have a Caregiver to be a little, adult baby, or a diaper wearer. If you feel like you're little then you could do things on your own to express how your feelings and mindset are to it.
Nonetheless, if you are looking to find a Caregiver or Daddy Dom (or...a Mommy Domme, if you're so inclined--they
do exist) then I'd suggest posting your personal ad here on Littlespace Online. There is a section dedicated to those of us who are seeking partners (physically intimate, nonsexual, romantically, platonic, etc). Just...join in!
Other than that, the Admin here created a wonderful resource post in the personals sections that is just unbeatable in terms of finding dating sites for ageplayers.
You can find a list of good AB / Ddlg / Mdlb / ageplay dating sites here:
