Erin, we adopted Zackary when he was 20 months old and Clara was 2 1/2(we adopted her as a newborn). I have a wealth of experience within the last 9 months I could share but no time to type it all here, lol!
I can tell you there was no transition time from his birthmother to us. We had lunch one day, dinner and an activity the next, placement the day after that. I think a longer transition would have been optimal but not available in our case. We did stay in San Antonio and attempted to visit with her as much as she was comfortable with while we were there.
*Find a therapist who specializes in infant/toddler mental health. Ours also specalizes in adoption related therapy. This resource will be invaluable to every member of the family. Probably not a bad idea to see someone like this even prior to accepting a placement.
Wish I could share more but I have to go again, and now, lol.....my leg slide doesn't work as well with one hand and the natives are restless! Feel free to email me @ andreaanddon@hotmail.com
