We got Mimi girl when she was 7 months old. We changed her name & she had no problems adjusting. She came from a home where they had 2 children & 1 teen, confined in the ex-pen or outside in the backyard most of the time & not fully potty trained. It took her another 2-3 months w/us to be fully potty trained. She still has 'issues' w/being in the ex-pen & going out into our backyard.
We do not have children in our home, so she had our undivided attention & love. One thing about Mimi tho, she loves being around children.
