Re: Just starting out
We recently started, too, but at 8 months. I do use a little potty, so can't comment on using a toilet seat, but to wipe, I either stand DS up by my leg and wipe him, or hold him kind of bent over my arm and wipe his bottom as I am putting him down.
Good luck and hope that helps a bit.
