Would you avoid this?

I kind of want to if we have a third, after having had an October baby (RIGHT after DD started preschool/childcare for the first time) as my second child. But then I kind of like that my kids will be older in their grade, I like that our whole family has birthdays near each other, and we had a relatively difficult time ttc#2 so I don't really want to worry about the timing so much. It's just that newborn part when they can't have a flu shot and they are so vulnerable that kind of bums me out. DS did have a short hospital stay for fever as a newborn (but he was fine.)

Not sure where to put this so I'm sticking it under TTC but it might belong somewhere else!!
