Baby seat in cockpit
We had the seat on the windward side tied in. But if the boat was heeling more than about 5 degrees, our daughter was in mom's arms. I did a lot of "accompanied solo sailing" for a couple of years.
When she was stable on her feet she could sit on the low side under the dodger and face which ever direction she wanted. A lot of times, she stayed in the v berth padded by pillows all around, and played with her toys.
