Moving in the the in-laws

Since we have lived in Florida we haven't been able to save as much money as we were when we lived in DC because I didn't have a job for a long time. We are by no means hurting for money but if we want to have a baby any time in the next year I would really like to have a lot saved up and be in a place where I wouldn't have to work right after the baby is born. No we are not pregnant yet but these are things I think about.

 Yesterday, E's mom told him that if we wanted to we could live with them for a couple of months rent free to help us save some money before we find a house. His parents live about 45 minutes from where E would be working and about the same for wherever I would find a job. Not a bad commute since we are used to DC Traffic. At first I was like no way we are not living with your parents for a couple of months. But the more that I think about it (the frugal side of me) thinks there really is nothing wrong this idea. His mom works in New Jersey Mon-Thrus. She she isn't even at the house expect on the weekends. She flys home on thursday evenings and then flys out early on monday morning. His step dad is a realtor. So it would just be the three of us during the week. I love his parents. The only thing I'm really afraid of is that if we live with them for a while that might change! I made a list of pros and cons and the cons seem pretty dumb. My worry is about my animals, Ashleigh hates any other dog besides the puppies and they have a dog. She has spent time there before but she is usually shut in our room there and that's no life for her. I guess she will just have to get over her fear. The other problem is that they don't have a fenced in back yard. Their dog is very well trained and doesn't leave the yard. My puppies are young and not so well trained. Mainly because they haven't had to be because we have a fence. So is 3 months of saving a ton of money worth it...I'm not sure but I need to decide before I leave so I know if I need to pack all my clothes or just some. :)
