Aww thanks about the picture! I actually just removed it to put a new one soon. Anyway, I had the snugli for my DD and it was a killer on my back!! The Baby Bjorn is about $80, but well worth it. I didn't believe all the hype about it not hurting your back. I was so surprised. You can put the baby facing you(I did this when he was sleepy, he fell right out)and foward facing. Front facing has alot of support for the head. this carrier is so easy to use and take on and off. I love it.
At home DS sleeps about as much as yours, sometimes maybe an hour more. We did drive straight through the night with DD when she was 8mo. No other kids at the time and we had MIL with us and her and DH took turns driving while I took care of DD. It worked out well. I would've done the drive at night, but lately DH and I just are too tired, and as I mentioned the worried mom in me!! Anyway, DH is use to being up at 5am to commute for 1hr+ so it worked well.
Ask as many questions as you want. I don't mind, I'm glad to help.
FYI when we drove srtaight through we left at 6pm and arrived about 3pm the next day. We stopped alot for DD.
Also, I hopped in the back seat and fed him his baby food sometimes. When it was time for a bottle we had to pull over. I had a bottle warmer travel kind that plugs into the lighter, it worked great. He's on special formula and it has to be mixed a certain way with cereal so I had to have the bottles premade and I kept them cold with icepacks like I do at home.
I should add that DS was a very sick baby, was premature and hospitalized 3 times at the age of 3mon. He almost didn't make it

Needless to say I was very worried about how he would do on the long ride and with his feedings and such. Everything worked out great. I'm sure your Ds will do fine.
