TTC around other child's birthday?

Do any of you have other children & you stop TTC a certain month because it'll be the same month as your other child?  My daughters bday is October & so I'm thinking if we didn't get pregnant this month to not try next month because I don't think I want my kids birthdays in the same month.  Anyone else do this- or not do this?
