My sister's kids will be 2 and 6 so her husband is going to board with the 6yo using the standard boarding procedures. I thought there might be a slight chance that they would allow all 4 of them to board together, but better safe than sorry.
That makes me wonder...what does the parent who boards with the child (and their car seat) do with the child while the car seat is being installed?? In our case, it won't be a big deal since there are 4 adults and one of us will be able to keep an eye on the child. I'm just wondering how solo parents would do it if the child is a pre-walker.
plop them on the seat you will be occupying. Or if there are two of you, one goes on first and then the second parent and child comes on toward the end.
