If traveling with DH, DS6 and DS18mo, will DS6 get to ride with me (those rides he can) and then ride again with DH after we swap baby? Or will DH have to ride alone? Thanks in advance!
I suggest doing it this way: Start with a normal child swap. When DH comes back with the first kid, do what you want. Only if someone asks questions, then you say "This person is staying behind", etc.
