Re: How to secure a baby
I second the car seat idea. We had my son out last year starting at 4 months old in a Rhodes 19 in his car seat. Most of the time he was still held, but it was nice to be able to have a place to put him down.
My second thought is a Pack 'n Play in the salon. Room to move around, high sides, place to put lots of pillows, blankets, etc. for cushioning if needed.
