I have two children, a son who is 4 and weighs 38 pounds and a daughter who is 21 months and weighs around 23 pounds. I have baby number 3 due October 21st (a huge suprise) we are trying to get a minvan but it may not happen and Im freaking out on how to fit all three kids in a 2004 Nissan Xterra. Right now my 4 yr old has a regent and my daughter has a comfortsport. Someone bought me a snugride carseat for the new baby. How do I fit three in the back? The regent is a beast and I really dont want to move my son to a booster yet so I have no idea what to do. On top of that I can not really afford to buy all brand new seats. This is really upsetting me and I need some advice
