I never paid attention to the baby swap threads because I never really thought they would pertain to me. DS is 15 and over 6 feet tall. He is pretty much fearless. I was talking with my brother and his wife the other day and we are planning a trip sometime in the distant future with them and their two little ones who are 4 and 2 now. My brother has some neck issues but his wife is an RN and knows his condition and what he can manage. We figure she will ride first and see if he can. Can baby swap work this way? She and I ride ToT for instance while DB and DS wait with DNs. Then when DSIL and I get off and we decide if DB can ride or not he and my DS will ride or just DS and maybe me or DSIL with DB sitting it out after all. Is this possible?
