ok, I have been thinking about another pup lately

harley is almost a year old and the best thing i could ever have asked for. no problems with training or tearing anything up, sleeping, etc.
anyway, i have been looking around (just curious) and i decided to email the breeder i got him from. i havent talked to her lately, i emailed her to ask her how everything was going and how her kids are and i asked if any more puppies were on the way.... i really felt she would not be having more puppies from our last conversation. she has been fostering "skin" babies and has been really busy. well she said in about 9 weeks she will be having puppies! the only dogs she has is harley's mom and dad and she was planning on getting the mom fixed but this pregnancy was not planned and she admits its her fault for not getting mom fixed which she plans on doing after these pups are born..... soooooo do you think this is a sign???? i mean if i was to get another i would really have wanted it to be from harley's mom and dad.....
i need opinions on having 2... honest pros and CONS. i have 2 cats and 2 children too ages 8 and almost 4. i am a stay at home mom.... i'm just so afraid to make a decision or even mention this to my hubby. about a month or so ago, i told him i was having puppy fever and his exact words were "ARE YOU CRAZY?"
