I Risked Too Much
Our gas light comes on, and I always reset it to see how far we go. I was travelling with my pregnant wife and two kids under 3. Why take the chance, right? Well, we pass one exit at 56 miles, and start stalling over the bridge. We coast 1 1/2 miles, but cannot make it to the next exit. Luckily, we were in Montgomery, AL on I-85 (about 5 miles until merging with I-65), and there are a lot of nice people there. One guy stopped right away, said he'd get gas, and came back. He bought a new can and filled it with gas and wouldn't take anything. Two other people stopped. One lady in a Lexus SUV who "just had to" seeing my wife 6 months pregnant and the two little ones. Amazingly, I didn't get much grief from the Mrs., but don't risk it over 50 miles. We did have the car packed for vacation and were blowing the AC full steam, so "your mileage may vary."
It's ok, just plan on making a lot of stops. You may want to rhitenk driving such a long distance if your baby is not one who normally falls asleep in a car seat. My husband and I drove 250 miles when my baby was that young and she screamed the whole time; we were absolutely miserable. But my daughter isn't the typical baby, she cries on the way to the market also which is only one mile away; she doesn't like to be confined to car seats. However, my sister's baby goes to sleep as soon as they hit the road. If your baby is like that, then you'll be fine. Maybe you should plan a mini trip first to test the baby out. Good luck!
