Is 22 too young to be a single foster parent?

Absolutely not! I got licensed within 6 months of turning 21 (our agencies minimum age requirement) and 5 years later we are still going! It can be awkward being the youngest, but we never had issues getting kids or anything. We are still doing young like you and always have a full home! I say if you feel ready, do it. Don’t put off helping the kids you want to help just because of age:) as long as you are stable in life, body and mind (no unmanaged health concerns) you should have no problems :) good luck!!
