I know it's not the safest idea (though now this marathon makes it even less safe). But what does everyone else do when your spending hours in the car with a toddler (possibly cranky) who will need a drink or a snack at some point? Do you pull over every time?
okay... the stickers, IMO, are to signal the section of bar for ninnies who would maybe otherwise have it setup to where the latch straps would not really be as tight as they seem and slip down to the right spot in a crash... and hey... there are some dads out there who can manage all kinds of misuse.
I think your install looks fine..
but onto this particular question.
I admit, one reason I loved getting my van was to make handing things back a little easier, BUT... when we had a sedan, Ruthie was in the center... and she was rf as we didn't get the van until she was almost 1yr old.
What I did then, for things like a binky, a blanket, her special bunny that played music, a cloth book, etc., was to hand it to my forward facing child and have it passed OR wait until I was stopped at a red light or could pull over.
Now, even once we had the van, while it was easier to reach her, I never handed her things while we were moving.
I would sometimes pass them behind me to my forward facing child (because I could do that without turning around) and had him pass it... if it wasn't a soft object (ie, a sippy), I waited, since he would have to toss it.
But then, when I moved her to the third row, it was even easier... I would pass to my 2nd row ff kid, who would pass it to his brother (this is when everyone was harnessed, so leaning was impossible for them), and he would give it to his sister.
but, when we were alone or when the boys were asleep... she had to wait till I could get over or stop or whatever.
If I knew ahead of time that she would get thirsty, I'd give her her sippy before I got in my seat and started the car.
But remember, your kid won't die of thirst or hunger or boredom because they have to wait 5-10min before they get what they want.
