The heart rules

If you want the second little guy I say go get him. The fact that they were raised together will certainly help. I tried two females at one time but it didn't work out because they weren't raised together and they were older (7 & 8 months). I agree you shouldn't be emotionally blackmailed but if you want him... get him. I have read that potty training can be easier if you plan on having two anyway because you get it all over with all at once. Good Luck on your decision.
