Normally, it is much better to leave the mare and foal on their own together for their first week or so together. At Longmeadow, we put new mares and foals in a stall in the quiet corner of the barn and interact with them as little as possible. It gives mom and baby important time to adjust to each other without human intervention. We do start working with the foals with haltering and leading alongside mom at about 2 week of age so they get used to it. But we always turn them out together alone too - they both need to get used to how to interact without human interference. I always did the same things when I raised horses for about 15 years.
Some are timid and some are bold and brave. That's another reason to limit the human interference at such an early stage. They need to learn to explore on their own and run back to mom for assurance. It's actually very important to early development of their personalities.
I'm sure they have good reasons for so much human presence at this early stage though.
Gardening is better than therapy. Plus you get tomatoes.
