Wasn't sure where to post this question, so here it goes. The wife and I are going to be working different shifts, and I will have to watch our twin daughters during the day. The only transportation I have is my 87 K5. Does anyone here run with child seats in the back seat. I want to know if the seat belts in the back seat are safe enought to hold 2 car seats. My girls are a little over a year and a half, so they will be facing the front. If anyone has any experience with this I would appreciate your input.
