has anyone adopted a foster baby here?

i adopted my 3rd foster child. he came to my home when he was 3 1/2 months old and his adoption was final when he was 2 1/2. before him i had a 4 month old until she was 13 months and another 9month old for a couple of weeks. currently i also have my son's 1/2 sister, but her bparents are working toward reunification.
