What do you think? What should be the time gap between two or more children? I think the difference between 2 and 4 years.Small but not very small difference in age means to save the psyche of all. You already have a good sleep ever since, as had the first child, so I think without a shudder of upcoming watches of the night. At the same time, it was still long enough that you forgot how to care for your baby. You have enough to think about the future, and clear parent philosophy (most importantly, not be allowed to second the kid used to sleep in the car, like his older brother). Big plus: you and your husband again even be able to find time for regular intimate relationships.
