I can fit 4 carseats and maybe one booster in my car but I only have 3 carseats (I supply them) so I only go out with 3 or less children. From my experience, parents LOVE that we go on field trips and they are all perfectly fine with short notice trips as well. In the summer we do a lot of walking field trips as I am close to 5 playgrounds, a splash park and an ice cream store/summer diner.

I have thought about taking the public transit as well but like you, I am hesitant. I know lots of daycare centres use the public transit but I just don't feel it's that safe. Plus I have never been on one myself so I admit, I am hesitant because I don't know how they work (as in which bus goes where lol)!!
