ignore them!! It isn't for everyone - people think I am mad for wanting 3 (I am only up to ttcno2 though) but if you can afford to support them and love them and take care of them then I don't see the problem with you have 3, 4, 5, 6 or 11!!
It's your choice not theres! Ive heard that the jump from 2 - 3 is lovely but ofcourse a bit more of a lifestyle change regarding changing cars etc. 3 is our magic number although I want a bit mroe of a gap between 2 and 3. (That is of course assuming I am blessed with no2!)
