You know within yourself whether your right to have another baby or not and you should follow that instinct. For me, I knew that no.4 was on his way and after I had him, I knew that he was my last. In answer he really his prolonging his babyhood (which is nice for me).

With no. 4 though there does come the issue of the family car, it's not suitable! You can't have family outtings, simply because legally there isn't enough seatbelts! You have to upgrade to a 7 or 8 seater.
