We do keep sessions with her short, about 10-15 minutes at a time. We also watch both her and mom for signs that they have had enough and back off when they show its time. We let her be a horse first and foremost. We don't bother her when she is asleep or eating, either. We are here all day long, so they are never really unattended, but I would not ever leave a halter on her for long, and certainly never unattended. We are doing our best to start her out right, partly from NOT doing what we saw others do wrong. She already lets us handle her, will cuddle with us, and is not afraid of us touching her or being around her. She has learned how to kick those back legs up, and we aren't encouraging that either. As cute as it is, I value my teeth.
